Prevalence and multimodal factors associated with impaired kidney function among persons with and without HIV in a routine clinic setting: a cross-sectional study.
Article in BMC research notes, 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
objectiveThis cross-sectional study aimed to determine the prevalence and factors associated with impaired kidney function (IKF), defined as an estimated glomerular filtration rate (eGFR) < 60 mL/min/1.73 m², in a mixed HIV serostatus cohort attending a routine care clinic at Livingstone University Teaching Hospital in Zambia. RESULTS DESCRIPTION: The overall prevalence of IKF was 12.0% (29/241) and was significantly higher in people living with HIV (PLWH) than those without (17.0% vs. 4.3%, p = 0.003). Sequential multivariable analyses revealed consistent associations. Multivariable analysis using a data-driven Firth’s penalized-likelihood logistic regression model identified HIV infection (Adjusted Odds Ratio [AOR] = 7.04; 95% CI 2.15–22.94; p = 0.001), increased interventricular septum diameter in diastole (AOR = 39.56; 95% CI 5.20-300.80; p = 0.0003), increased right ventricular dimension in diastole (AOR = 6.01; 95% CI 1.64–22.03; p = 0.007), and higher serum uric acid levels (AOR = 1.01 per mmol/L; 95% CI 1.00-1.01; p = 0.009) to be independently associated with IKF. A clinical model confirmed associations with older age, HIV, and higher fasting blood sugar. When adjusting for these clinical factors, higher levels of soluble ST2, uric acid, and spot microalbumin remained significantly associated with IKF. This study reveals a high burden of undetected kidney impairment in a routine clinic setting, disproportionately affecting PLWH. These findings warrant validation in larger prospective studies.
