Determinants of HIV related mortality in African children on antiretroviral therapy: clinical and immunological insights from a systematic review and meta-analysis.
Synthesis in AIDS research and therapy, 2025. 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
backgroundThe HIV epidemic in Africa is still a serious public health concern, particularly for children who are more vulnerable to its negative consequences. Various studies carried out in different African nations have shown associations between these variables and increased mortality risk in children receiving antiretroviral therapy. However, the magnitude and consistency of these effects across different settings in Africa remain unclear, with a few studies reporting nonsignificant effects of advanced disease stage and immunological factors on mortality. This review is the first to provide a thorough analysis of the determinants of HIV-related mortality in children.
methodsThis review followed the PRISMA guidelines, and relevant studies were obtained from the PubMed, CINAHL, EMBASE, and Google Scholar databases. Study selection, data extraction, and quality evaluation were carried out separately by two reviewers. A heterogeneity-based meta-analysis was conducted using random effect models. A sub group analysis was done based on age group and country.
resultsA total of 36 studies involving 198,957 study participants were included in the review. Advanced disease stage (WHO III/IV) (HR 3.45; 95% CI 2.17-5.48), TB coinfection (HR 2.12; 95% CI 1.53-2.92), opportunistic infections (HR 2.04; 95% CI 1.59-2.62), immunosuppression (HR 2.50; 95% CI 2.01-3.11), and poor medication adherence (HR 3.36; 95% CI 2.10-5.38) and lack of cotrimoxazole use (HR 2.2; 95% CI 1.14-4.26) were significantly associated with a greater risk of HIV-related mortality.
conclusionThis review revealed key clinical, immunological, and treatment-related predictors of HIV-related mortality in children in Africa, including advanced disease stage, TB co-infection, immunosuppression, poor adherence, and lack of cotrimoxazole use. To reduce HIV-related child mortality in Africa, health policies should strengthen pediatric HIV care through context-specific service delivery. This includes early identification of advanced disease, management of opportunistic infections, access to cotrimoxazole prophylaxis, and age-appropriate adherence support, especially in under-resourced settings.
