Retrospective analysis of CD4 trends at district levels in South Africa between 2013 and 2023.
Article in Southern African journal of HIV medicine, 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
Background: South Africa has the largest HIV epidemic globally. Despite the scale-up of antiretroviral therapy, people living with HIV still present with CD4 ≤ 200 cells/µL because of possible treatment interruptions and/or late presentation. Objectives: This study assessed the proportion of CD4 specimens with counts ≤ 200 cells/µL by health district, comparing 2013 to 2023. Method: This cross-sectional study analysed laboratory data. Annual test volumes, median CD4 and the percentage of specimens with a count ≤ 200 cells/µL were reported. The difference in the median CD4 between 2013 and 2023 was calculated. No de-duplication was possible because of the absence of unique identifiers. Results: Data are reported for 5 821 932 specimens, with a significant decline in absolute numbers, while the percentage of specimens with a count ≤ 200 cells/µL declined by 0.4%. The median CD4 increased from 396 cells/µL in 2013 to 465 cells/µL by 2023. Between 2013 and 2023, eight districts showed a decrease in the median CD4, while 44 reported an increase ranging from 2 cells/µL (Sedibeng) to 192 cells/µL (uThukela). A percentage point reduction for counts ≤ 200 cells/µL between 2013 and 2023 was reported for 23 districts (44.2%), while 29 (55.8%) showed a percentage point increase. Conclusion: Despite an upward trend in the national specimen-level CD4 count median over time, unacceptable levels of CD4 counts ≤ 200 cells/µL persisted. The analysis provides important insight into district burden of advanced HIV disease which warrants national attention and further investigation.
