Forest plot

A forest plot is a visual tool used in research to display the results of multiple scientific studies on the same topic. It shows each study's estimated effect (such as treatment benefit or risk) along with its confidence interval, which indicates the precision of that estimate. The plot typically includes a line representing no effect, so you can quickly see whether studies favor one outcome or another. By summarizing many studies in one chart, a forest plot helps researchers and clinicians assess the overall evidence and identify patterns or consistency across different research findings.
