Characteristics of Individuals With Advanced HIV Disease and Risk Factors for Mortality in a Contemporary Cohort in South Africa.
Article in Journal of acquired immune deficiency syndromes (1999), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundAdvanced HIV disease is a major contributor to the slowing decline in HIV-related deaths globally. However, limited data exist on which individuals with advanced HIV are at highest risk of death.
methodsA retrospective cohort study was nested within a larger cohort of 13 primary care HIV treatment facilities in Khayelitsha, South Africa. All adults who had a CD4 count <200 cells/mm 3 between January 1, 2017, and March 31, 2021, were enrolled. Descriptive statistics were calculated, and the cohort was then restricted to those who had linked vital status information. We evaluated risk factors for mortality using Kaplan-Meier curves, and univariable and multivariable Cox proportional hazards models.
resultsBetween 19% and 28% of the larger cohort (n = 72,102) were estimated to have advanced HIV disease at any point during the study period. Of these individuals, 20% were on treatment, 40% were disengaged from care, and 40% were treatment naive at enumeration. Overall mortality was 12%, with mortality highest in the first year (6.8%) after enumeration. There were 608, 371, and 370 deaths among those disengaged, on antiretroviral therapy (ART), and ART naive, respectively, representing 14%, 17%, and 8% of individuals in each group. More than a quarter of all participants were found to have current tuberculosis at enrollment into the cohort.
conclusionsART-exposed individuals with advanced HIV disease contribute substantially to ongoing HIV-related mortality in South Africa. Improved adherence and retention strategies within HIV programs could reduce this mortality.
