Topic: Confidence Intervals
1) Definition: confidence interval allows us to measure the uncertainties involved in estimating population parameters. It is typically calculated based on sample data and includes two key elements:
Confidence Interval: This consists of two numbers representing the range within which we can expect to find the true population parameter.
Confidence Level: Usually expressed as a percentage (e.g., 95%), it indicates the probability that the calculated interval correctly captures the true parameter.
2) Conceptual Interpretation:
If we say that a 95% confidence interval for the mean of a population is 50 to 60, this means that if a large number of similar random samples were taken, in 95% of the cases, the true population mean would fall within this interval. Therefore, this tool is crucial for documenting decision-making in statistics and management.
3) Advantages and Applications:
Ease of Understanding: Confidence intervals aid in interpreting statistical results and highlight the uncertainty inherent in conclusions.
•Decision-Making in Policy: In policymaking, confidence intervals. allow analysts to account for fluctuations in data and the decisions based on them.
•Research and Development: In scientific research, confidence intervals help researchers understand the accuracy of their findings, leading to more precise scientific publications.
4) Limitations:
Need for Large Sample Size: When the sample size is small, confidence intervals may have less reliability.
Distribution Assumptions: It is commonly assumed that the data follow a normal distribution. If these assumptions about the distribution of the data are violated, we can obtain incorrect results.
•Reliance on Confidence Level: Misinterpretation of the confidence level can lead to misunderstandings. For example, 95% confidence does not mean that the answer is correct in 95% of cases.
5) Conclusion:
Confidence intervals are a vital tool in statistics that help us quantify the uncertainties associated with estimating population parameters. They are a powerful instrument in statistics for estimating population parameters and understanding fluctuations in data. A correct understanding of how to use and interpret them can contribute to more accurate analyses and more informed decision-making.

*Handling non-English studies*
Systematic reviews (SRs) are a vital source of evidence for healthcare interventions; however, there is limited research on the contribution of non-English reports. Researchers sometimes choose to exclude these references, but doing so can introduce bias—commonly referred to as “English-language bias” or the “Tower of Babel bias”—especially in globally relevant fields or when non-English studies report different outcomes or effect sizes.
Several papers propose specific solutions. Some emphasize the value of machine translation tools such as Google Translate and other free or low-cost platforms. Others recommend leveraging human resources, such as volunteer students or multilingual/international research teams. Studies with funding may also employ professional translators or specialized translation services.
Overally, there is strong consensus that researchers should avoid language-based exclusions to ensure more comprehensive scientific findings.

#gliomasheadache
💠 Gliomas are the most common primary tumours of the CNS, and are classified according to morphologic
criteria established by the WHO into various histologic subtypes and grades, including:
🔹 Astrocytomas,
🔸Oligoastrocytomas
🔹Oligodendrogliomas
🔅 Headache is observed in approximately 20% of patients with glioma at disease onset
🔅 In patients with glioma, headache at onset may be similar to tension-type headache, especially in older people.
🔅 Infratentorial and right-sided gliomas are more frequently associated with the presence of headache at onset (infratentorial gliomas were frequently associated with headache, probably because of cerebrospinal fluid flow
dysfunction and consequent increased intracranial pressure)
💠 BTH (Brain Tumor Headache) was defined as a progressive headache,
occurring daily or intermittently, and with at least one of the following three characteristics:
1⃣ Worse in the morning
2⃣ Triggered or aggravated by Valsalva-like manoeuvres
3⃣ Associated with nausea and/or vomiting
❗️Its clinical features are not so specific and sometimes satisfy the criteria for primary headache such as migraine or tension-type headache
💠 Other neurological signs and symptoms:
🔸 cognitive alterations
🔹 seizures
🔸 imbalance
🔹 sensory-motor disturbances
🔸 visual field deficits
💠 Management Strategies:
1⃣ Tumor-targeted treatments:
🔸 Surgery:
Maximal safe resection of the tumor is a primary goal, especially for gliomas that are accessible and do not involve vital brain structures.
🔹 Radiotherapy:
Radiation therapy is often used after surgery to target and destroy remaining tumor cells.
🔸 Chemotherapy:
Chemotherapeutic agents, such as temozolomide, are frequently used in high-grade gliomas to slow tumor growth and improve survival.
2⃣ Headache-specific interventions:
🔹 Analgesics:
Over-the-counter pain relievers (acetaminophen, ibuprofen) and prenoscription opioids (oxycodone) can help manage pain.
🔸 Steroids:
Dexamethasone and other steroids can reduce swelling in the brain, which can alleviate headache pain.
🔹 Neuromodulation:
Techniques like transcranial magnetic stimulation (TMS) or nerve blocks may be considered in some cases.
3⃣ Supportive care:
🔸 Palliative care:
Specialist palliative care services can provide comprehensive symptom management, including pain control, and emotional support, particularly for patients with high-grade gliomas.
🔹 Rehabilitation:
Physical, occupational, and psychological therapies can help patients manage functional deficits and improve their quality of life.
🔸 Behavioral interventions:
Techniques like relaxation training, biofeedback, and cognitive behavioral therapy (CBT) can help patients cope with pain and other symptoms.

🔹 P-values in Plain Language
🔸 Introduction
The validity of a scientific conclusion in a research paper should depend on more than just statistical analysis. Not only the appropriate application of statistical methods, but also the correct interpretation of results plays a critical role in drawing sound conclusions. To support the significance of a study’s findings, the concept of statistical significance—typically assessed by an index known as the p-value—is commonly used.
🔸 What is a P-value?
The p-value is defined as the probability of obtaining data as extreme as, or more extreme than, what was observed, assuming that the null hypothesis is true.
P-values are used to gauge the strength of statistical evidence in many scientific studies. They indicate the likelihood that a result as extreme as the observed one could occur purely by chance. While p-values help report the outcome of statistical tests, they do not convey the practical importance of those results.
They depend on a test statistic, a null hypothesis, and an alternative hypothesis. Multiple testing and selective analysis of subgroups, outcomes, or variables can produce misleading p-values. Full transparency and statistical corrections can help minimize such errors. Additionally, negative studies with low statistical power can lead to incorrect conclusions about the ineffectiveness of medical interventions.
🔸 Threshold for P-values
To statistically infer whether a result is significant, researchers estimate the probability of obtaining such a result purely by chance under the null hypothesis. A historically accepted threshold for rejecting the null hypothesis is 0.05.
Accordingly, if the p-value is <0.05, researchers often celebrate a “eureka” moment by rejecting the null and accepting the alternative hypothesis.
The p-value reflects the probability that an observed effect occurred by chance when, in reality, no true effect exists. Conventionally, p-values <0.05 or <0.01 are considered statistically significant. Although some argue this threshold should be lowered, it remains widely used in practice.
🔸 Key Recommendations When Using P-values
1️⃣ Report effect sizes and confidence intervals
Don’t rely on p-values alone. Reporting effect sizes provides insight into the magnitude and practical relevance of the effect.
2️⃣ State the null hypothesis clearly
Specify what the p-value represents—whether it's a one-tailed or two-tailed test—and how it relates to the null hypothesis.
3️⃣ Interpret p-values in the context of sample size
Large samples can produce significant p-values even for small effects, while small samples might miss significant findings. Consider statistical power relative to the expected effect size.
4️⃣ Be cautious with multiple comparisons
Running many tests increases the chance of false positives (Type I error). Adjustments (like Bonferroni correction) should be made to control error rates.
5️⃣ Check test assumptions and conduct sensitivity analyses
All statistical tests rely on assumptions (e.g., normality for t-tests). Violating these can invalidate your results. Use appropriate tests or data transformations as needed.

Epilepsy is a neurological disorder characterized by recurrent seizures, and electroencephalogram (EEG) signals play a vital role in its diagnosis. Manual analysis of these signals is time-consuming and prone to human error, so using deep learning for automated detection can improve accuracy and efficiency.
Study Objective
This research aims to develop a deep learning model to classify EEG signals into three states:
1. Ictal state (during an epileptic seizure)
2. Interictal state (brain activity before a seizure)
3. Normal state (non-epileptic brain activity)
Methodology
1. Data Used
- EEG recordings from epilepsy patients, including both seizure and non-seizure data.
- Signals were segmented and labeled to be suitable for supervised learning.
2. Data Preprocessing
- Noise removal (e.g., muscle activity or other artifacts).
- Normalization to standardize signal amplitudes.
3. Feature Extraction
- A 1D Convolutional Neural Network (1D-CNN) was used to automatically extract key features from raw EEG signals.
- These networks are highly effective in identifying spatial and temporal patterns in EEG data.
4. Classification Model
- A hybrid deep learning approach was employed, combining CNN with Long Short-Term Memory (LSTM) or a Transformer-based architecture to process sequential EEG data.
- The model learns to distinguish between EEG patterns associated with seizure, interictal, and normal states.
5. Model Training and Evaluation
- The model was trained on labeled data, and its generalizability was tested.
- Evaluation metrics included Accuracy, Sensitivity, and Specificity.
Results
- The proposed model achieved over 95% accuracy in classifying epileptic EEG signals.
- It outperformed traditional machine learning methods (e.g., SVM, Random Forest) and simpler neural networks.
- The CNN-Transformer combination demonstrated particularly strong performance in identifying long-term dependencies in EEG signals.
Significance and Applications
- Early seizure detection: Useful for real-time monitoring of epilepsy patients.
- Automated diagnosis: Reduces reliance on manual EEG analysis, improving speed and consistency.
- Integration with wearable EEG devices for continuous patient monitoring.
Conclusion
This study demonstrates that deep learning, particularly hybrid CNN-based models, can classify epileptic EEG signals with high accuracy. This approach holds promising applications in clinical settings to improve epilepsy diagnosis and treatment.

🔶 The Evolving Role of Neuroprostheses in Spinal Cord Injury Recovery
Neuroprostheses—devices that directly communicate with the nervous system via electrical impulses—are significantly advancing rehabilitation for spinal cord injuries (SCIs). According to Mayo Clinic physiatrist Dr. Ryan J. Solinsky, over the past 11 years, both implanted epidural and noninvasive spinal cord stimulation have regained functions once thought impossible .
– Epidural stimulation (2018 study): Enabled assisted walking and improved trunk control.
– Transcutaneous stimulation (2024 study): Enhanced hand strength and grip in chronic tetraplegia.
These breakthroughs are redefining recovery expectations and elevating patient care with smarter, more personalized interventions.

Effect Sizes Explained Simply
Effect size is a statistical measure that quantifies the strength or magnitude of a relationship or difference between groups. Unlike p-values, which only tell us whether an effect exists, effect sizes show how large that effect is. For example, in comparing two treatments, a large effect size indicates a substantial difference, while a small effect size suggests minimal impact—even if statistically significant.
Common effect size measures include Cohen’s d (for mean differences), Pearson’s r (for correlations), and odds ratios (for categorical outcomes). Understanding effect sizes helps researchers interpret the practical significance of their findings and compare results across studies, which is especially useful in meta-analyses.
By focusing on effect sizes, scientists and readers can make more informed decisions beyond statistical significance alone, ensuring that results are both meaningful and applicable.

#Resolving_disagreements_in_screening
❓ 1. What is the definition of screening and resolving disagreements?
Screening is when reviewers check noscripts and abstracts of articles based on inclusion and exclusion criteria. If they disagree, they discuss or ask a third reviewer to decide.[1]
---
❓ 2. What is the purpose of this method?
This helps prevent irrelevant articles from entering the review. It improves accuracy and makes the results more reliable since decisions are checked by more than one person.[2]
---
❓ 3. What are the problems and contradictions in this method?
Reviewers may interpret criteria differently or make mistakes due to fatigue. Also, not clearly recording reasons for exclusion can lower the quality and trust in results.[3]
---
❓ 4. Can you give some examples?
For example, using Covidence software for double screening, checking reviewer agreement with Cohen’s kappa, and writing clear reasons for exclusion in a step-by-step order, like in WHO or Cochrane reviews.[4]

📌 Topic: Visual Abstract for Review Articles
♦️ Introduction:
A Visual Abstract is, simply put, a graphical summary of the information presented in a paper’s abstract. These abstracts leverage the human brain’s innate ability to quickly process and retain visual information.
Visual abstracts—also known as Graphical Abstracts (GA)—have become powerful tools for effectively communicating complex ideas in a simplified and concise manner. Their use is increasingly expanding, especially on social media platforms.
⸻
🎯 Objectives of a Visual Abstract:
• To simplify methodologies and summarize key findings for quick and effective comprehension
• To enhance interpretation, retention, and shareability of research content
• To highlight the core message of the article by removing non-essential details
⸻
🔹 Main Components of a Visual Abstract:
• A noscript that reflects the central research question or objective
• A summary of key results, including comparisons, data, and visual representations
• Names of the authors and the visual abstract designer
• A three-panel layout using clear, simple, and monochromatic icons for improved clarity
⸻
🔹 Types of Graphical Abstracts:
1. Conceptual Diagrams
2. Flowcharts
3. Infographics
4. Iconographic Abstracts
5. Photographic Visuals
⸻
🔷 Steps to Design an Effective Visual Abstract:
1. Identify the core message of the article
2. Select an appropriate visual style for the study type
3. Create a simple, clear, and understandable graphic layout
4. Use color and design elements thoughtfully
5. Seek feedback to refine and finalize the design
⸻
🔷 Benefits of Using Visual Abstracts:
• Assisting in early decision-making about whether to read the full article
• Increasing article visibility on social media and attracting a broader audience, especially those with limited time or scientific background
• Facilitating discussion and knowledge exchange around the research findings
• Enhancing citation rates and research impact, as supported by various studies.
⸻
⚠️ Challenges and Limitations:
• Risk of oversimplification and omission of important information
• Possibility of misinterpretation or incomplete message transmission
• Requirement of graphic design skills alongside scientific understanding
⸻
🔸 Conclusion:
Just like textual abstracts cannot replace the full article, visual abstracts are not intended to serve as substitutes either. They offer a snapshot of the study’s key points to help the reader decide whether the full article is worth reading and assist in the understanding of essential concepts.
The format of visual abstracts is still evolving, which leaves room for creativity and flexibility in their design.
Among the useful tools, genetic algorithms can be considered valuable for conveying complex data in a clear and concise visual form. These algorithms have the potential to make scientific content more accessible and engaging to a wider audience. In today’s media-driven world, mastering such tools has become a kind of creative skill—one that promises a progressive future for academic publishing despite certain limitations.

🧠Surgical Planning Assistance Using Neural AI
🔹Neural artificial intelligence is rapidly transforming the way surgical planning is performed. By analyzing large volumes of medical images (such as CT and MRI scans), neural networks can help surgeons visualize anatomical structures more clearly and predict potential complications before the operation.
🔹For instance, convolutional neural networks (CNNs) can automatically segment organs and tumors, creating accurate 3D models that assist in pre-operative decision-making. These tools reduce the risk of human error and improve surgical precision, especially in complex procedures like neurosurgery or oncology.
🔹Furthermore, AI can simulate different surgical scenarios, allowing surgeons to choose the safest and most effective approach. While these technologies are not meant to replace human expertise, they act as intelligent assistants that enhance surgical outcomes and patient safety.
