FIGURE 1.
Forest plot of the association between treatment with an angiotensin-converting-enzyme inhibitors and/or AT1 blockers and all-cause mortality/severe disease in patients with coronavirus disease 2019. The figure shows effect estimates of outcomes (boxes) with 95% confidence limits (bars) for each study selected; pooled relative risk for cohort studies and pooled odds ratio for case–control studies is represented by a diamond in this forest plot. The confidence intervals for some studies may differ slightly due to log transformation of all effect estimates.
