Forest plot of mortality among patients successfully traced in 32 cohorts of patients LTFU in ART programmes in sub-Saharan Africa. Study-specific mortality estimates are shown with exact binomial 95% confidence intervals. The studies are ordered by the mid-point of the study periods. Mortality among LTFU patients that were successfully traced decreased over time. The size of each square is inversely proportional to the variance of the estimate for that study.
