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
objectiveTo analyze the temporal trend of epidemiological indicators and factors associated with tuberculosis treatment dropout and death among street people.
methodsThis is a cross-sectional study on tuberculosis among street people in Brazil from 2014-2022, using data from the Notifiable Health Conditions Information System (Sistema de Informação de Agravos de Notificação). We calculated cure, dropout, incidence and mortality indicators. The temporal trend of the indicators was estimated using Prais-Winsten regression, expressed via average percentage change (APC). Notification form variables were used to estimate factors associated with tuberculosis treatment dropout and death using logistic regression, resulting in odds ratios (OR) and 95% confidence intervals (95%CI).
resultsIn all, 21,904 tuberculosis cases were reported. In Brazil as a whole, APC for cure was -5.8% (95%CI -7.9; -3.8), while in the Southeast region, APC for incidence was -6.2% (95%CI -8.9; -3.5) and for mortality it was -5.3% (95%CI -10.0; -0.4). Predictors of dropout were: absence of directly observed treatment (OR 3.92; 95%CI 3.65; 4.20), being 20-39 years old (OR 1.81; 95%CI 1.41; 2.33) and use of illicit drugs (OR 1.57; 95%CI 1.46; 1.69). Factors associated with death were: absence of directly observed treatment (OR 3.18; 95%CI 2.86; 3.54), being >60 years old (OR 3.14; 95%CI 2.14; 4.61) and use of illicit drugs (OR 1.18; 95%CI 1.05; 1.34).
conclusionThe tuberculosis scenario in this population is worrying and its challenging context requires greater effort to achieve better screening and treatment, considering the multiple risk factors identified.
