Forest plot of study and summary effect estimates for cotrimoxazole’s effect on death in adults with human immunodeficiency virus (HIV) infection receiving antiretroviral therapy (ART)

Note: The seven studies were included in the meta-analysis. The summary estimate of the treatment effect was calculated using a random-effects model. The risk is reported either as an odds ratio, a hazard ratio or a relative risk in the different studies. The centre of the squares represents the study point estimates while the horizontal lines represent the study 95% confidence intervals (CIs). The centre of the bottom quadrilateral represents the summary effect estimate, whereas its horizontal corners represent its 95% CI.
