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
introductionTuberculosis (TB) continues to be a significant public health issue, particularly in low-income and middle-income countries. Globally, the End TB Strategy targets an 80% reduction in TB incidence by 2030. Despite this strategy, there remains limited evidence on the incidence of TB among HIV-infected children after the test-and-treat strategies in Amhara Region. Hence, this study aimed to assess the incidence of TB and its predictors among children on antiretroviral therapy (ART) in Amhara Region, which is the second largest region in Ethiopia and located in the northwestern, northeastern and north-central parts of Ethiopia.
methodsA multicentre institution-based retrospective follow-up study was conducted on 421 HIV-infected children receiving ART from July 2014 to March 2022. The study participants were selected using simple random technique. National antiretroviral intake and follow-up forms were used to gather data through the KoBo Toolbox. Stata V.17 was used for data analysis. The Kaplan-Meier curve was applied to estimate failure time, and the log-rank test was employed to compare groups of predictors. To identify TB predictors, Gompertz regression models, both bivariable and multivariable, were constructed. Ultimately, a 95% CI adjusted HR (AHR) was calculated, and variables with a p value less than 0.05 were considered statistically significant.
resultsA total of 421 children with a record completeness rate of 97.9% were analysed in the study. The TB incidence rate in children on ART was 2.16 (95% CI 1.52, 3.05) per 100 child-year observations. Anaemia at baseline (AHR: 3.83; 95% CI 1.46, 10.04), never taking TB preventive treatment (TPT) (AHR: 3.78; 95% CI 1.44, 9.94), wasting (AHR: 2.53; 95% CI 1.19, 5.38) and not initiating ART within 7 days (AHR: 2.35; 95% CI 1.15, 4.78) were significant predictors of TB in children.
conclusionThe incidence of TB in children on ART was relatively high. HIV-positive children presenting with anaemia, those who never took TPT, wasted children and those with late initiation of ART were prone to the occurrence of TB. Therefore, prioritising anaemia treatment, TB preventive therapy, nutritional counselling and timely initiation of ART are essential to curb the TB burden.
