Uptake and disparities in tuberculosis screening using urine-lipoarabinomannan among patients with advanced human immunodeficiency virus-disease in Africa: A systematic review.
Article in World journal of virology, 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
backgroundDue to low bacteria count and high likelihood of having extrapulmonary tuberculosis (TB) among patients with advanced human immunodeficiency virus (HIV) disease, the World Health Organization (WHO) recommended the use of urine lateral flow urine lipoarabinomannan (LF-LAM) or sputum-Xpert to screen for TB.
aimTo estimate pooled prevalence of TB screening uptake, TB diagnosis, TB treatment initiation and mortality among patients with advanced HIV disease in Africa.
methodsPubMed, Cochrane Library and EMBASE were searched for articles published between January 2011 and December 2024. TB screening uptake was defined as percentage of patients with advanced HIV disease (CD4 ≤ 200 cells/mm
resultsA total of nineteen studies with 16065 people with advanced HIV disease were analyzed. The pooled prevalence of TB screening uptake was 64.6% (95%CI: 49.2-80.1). The pooled prevalence of TB was 29.4% (95%CI: 22.0-36.8), and TB treatment initiation was 77.9% (95%CI: 63.9-91.8), and mortality was 19.5% (95%CI: 8.9-30.0). The pooled prevalence of TB testing uptake was significantly lower among children compared to adults (28.2%
conclusionFour in ten people with advanced HIV disease were not screened for TB as recommended by the WHO, indicating significant gaps in identifying patients with TB. Excluding patients with evidence of TB is critical to avoid exposing them to subtherapeutic levels of anti TB treatment.
