Mean and Mean difference are the two key statistical measures used in the statistical analysis. Both are essential for meta-analysis as well. Mean and Mean difference are used for the interpretation of a large set of values into a single number which explains the heterogeneity and variation among the individual values. However, one of a common challenge in meta-analysis is the unavailability of this data (mean and standard deviation).

Q: Understanding Review articles: Types, significance, and better Practices
Introduction
Numerous assume that writing a review composition is a simple task — simply recapitulating available literature. Still, casting a high- quality review composition requires critical thinking, clear objects, expansive exploration, and strong writing efficiency. Different types of research review papers exist, each plays a crucial role in creating scientific knowledge.
This article highlights different types of research review papers and their part in Evidence-based research, the importance of SR and MA, and best practices for conducting them
Types of Review Articles
Review papers come in multiple formats, each with a distinct methodological approach and purpose.
- Systematic Reviews and Meta- Analyses
Methodical Reviews: These are qualitative secondary exploration studies that follow a rigorous and structured methodology to minimize bias while reviewing being literature.
Meta- Analyses: These incorporate quantitative statistical analysis, pooling data from multiple studies to give a more robust assessment of an exploration question.
Example: A methodical review on the effectiveness of telemedicine in habitual complaint operation may dissect randomized controlled trials, while a meta- analysis may statistically combine patient issues from different studies.
- Umbrella Reviews
Also known as” overviews of reviews”, these synthesize findings from multiple methodical reviews, offering a high- position summary of being substantiation.
Illustration: An umbrella review might collect data from multiple methodical reviews on the impact of diet on heart complaint.
- Rapid Reviews
occasionally called” quick scoping reviews”, these give a streamlined interpretation of a methodical review by using time-effective styles while maintaining scientific rigor.
Example: A rapid review may be conducted during public health extremities, similar as assessing the effectiveness of COVID- 19 treatments.
- Narrative Reviews (Traditional Reviews or Literature reviews)
These reviews epitomize and critically discuss available literature without strict systematic constraints. They frequently give background information and contextual analysis.
Example: A narrative review on artificial intelligence in healthcare may explore arising technologies, their operations, and ethical considerations.

- Scoping Reviews
Scoping reviews totally collude the literature on a broad content, relating crucial generalities, gaps, and trends. Unlike methodical reviews, they do not concentrate on assessing the quality of substantiation.
Example: A scoping review might dissect global exploration trends in internal health interventions for adolescents.
- Critical Reviews
Critical reviews go beyond summarization, taking in- depth evaluation of literature quality to decide new hypothesis or identify abstract gaps.
Example: A critical review might evaluate biases in clinical trials on pain operation and propose optimized methodologies.
- Overviews
Overviews present a chronological, abstract, or thematic summary of medical literature, offering perceptivity into how knowledge has evolved over time.
Example: An overview of cancer treatments may track advancements from chemotherapy to targeted gene treatment.
- State- of- the- Art Reviews
These expert- driven reviews give a comprehensive update on the recent advancements in a field, frequently guiding future exploration.
Example: A state- of- the- art review on robotics in surgery may consider cutting- edge inventions and their clinical operations.
