In evidence-based medicine, systematic reviews and meta-analyses are often mentioned together but they are not the same thing. Think of them as two related steps in understanding research evidence.

A **systematic review** is a structured, methodical summary of all available original research on a specific question.

It involves:

- A clearly defined research question (PICO[TS])
- Comprehensive literature search
- Predefined inclusion and exclusion criteria
- Critical appraisal of study quality
- Qualitative synthesis of findings

The primary goal is to answer what the evidence says and how reliable it is.

> A systematic review may exist with or without a meta-analysis.

A **meta-analysis** is the statistical part of a systematic review.

It involves:

- Combining numerical data from multiple studies
- Calculating pooled effect sizes
- Presenting results using forest plots
- Improving statistical power and precision

The goal is to answer how strong the effect is using numbers.

> A meta-analysis cannot exist alone, it must be based on a systematic review.

The key difference is,

Systematic review =\> Structured search + critical evaluation

Meta-analysis =\> Statistical combination of results

> All meta-analyses are part of systematic reviews, but not all systematic reviews include a meta-analysis.

Understanding this distinction helps one to:

- Interpret evidence correctly
- Avoid confusing narrative summaries with pooled statistics
- Choose the right method for research and publications

> Systematic review builds the evidence story whereas Meta-analysis adds numerical strength to that story.

Meta-analyses incorporate statistical pooling for precise impact sizes using forest plots, while systematic reviews systematically synthesis all the data through organized search and quality evaluation. Understanding both improves the interpretation of the evidence, but not all reviews require meta-analysis because heterogeneity frequently prevents it.
