A Forest Plot table (combining odds ratios from multiple studies with a summary diamond) represents which type of study?
Show answer and explanation
Correct answer: A. Meta-analysis
- A. Correct. A FOREST PLOT is the graphical output of a META-ANALYSIS — it displays the effect sizes (e.g., odds ratios) from multiple individual studies, their confidence intervals, and a summary DIAMOND at the bottom representing the pooled combined effect. The diamond's position indicates the overall direction of the effect; its width represents the confidence interval.
- B. Incorrect. A forest plot combines results from MULTIPLE studies — it is not itself a cohort study.
- C. Incorrect. A systematic review is a qualitative synthesis — it may or may not include a meta-analysis. A forest plot is specific to the statistical meta-analysis component.
- D. Incorrect. Cross-sectional studies report prevalence data — not combined odds ratios from multiple studies.
