Human immunodeficiency virus in chronic limb-threatening ischaemia: Risk factors, management, and outcomes: A South African retrospective cohort study.
Article in Journal of the colleges of medicine of South Africa, 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: People living with human immunodeficiency virus (PLHIV) have an increased risk of chronic limb-threatening ischaemia (CLTI), yet data from sub-Saharan Africa in the modern antiretroviral era remain limited. We estimated the human immunodeficiency virus (HIV) prevalence in patients admitted with index CLTI and compared risk factors and outcomes with those of their seronegative counterparts. Methods: Retrospective study of adults admitted with CLTI to Tygerberg Hospital (2016-2022). Patients identified via discharge summaries were corroborated with medical records. Clinical and HIV status data were extracted from medical and laboratory records. Results: Among 1205 patients admitted with index CLTI, the estimated prevalence of HIV was 3.5% (95% CI: 2.5% - 4.7%), with 588 confirmed HIV-negative (48.8%) and 575 with unknown HIV status (47.7%). The PLHIV cohort was 69% male compared to 64% in the HIV-negative group ( Conclusion: People living with HIV were younger and had fewer risk factors for CLTI than their HIV-negative counterparts. In-hospital revascularisation outcomes, complication rates and mortality were similar. Contribution: Further study is needed regarding the district hospital HIV burden and long-term outcomes in these patients.
