The lowest mortality rate in the published literature from low and middle-income countries from tracking studies of ART patients presumed LTFU is 27% and the highest mortality is 87% [39, 40].
In a meta-analysis of 17 studies from low and middle-income countries by Brinkhof et al. [41] the combined mortality of ART patients from tracking studies of patients presumed LTFU was 40% (95% CI: 33–48%).
