Forest plot of adjusted Risk Ratios reprinted with permission from Byakika-Tusiime (8), AIDS and Behavior, vol. 12, page 838 (reprinted with permission, Springer Science and Business Media). The squares represent the individual studies and the horizontal lines represent the 95% confidence intervals. The size of each square is proportional to the study’s weight in the meta-analysis. The dotted vertical line represents the overall meta-analyzed measure of effect. The diamond represents the pooled/combined effect after meta-analysis and the 95% confidence interval. The solid vertical line represents no effect.
