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
backgroundDespite increasing use of Gene Xpert diagnostics, recent evidence on TB prevalence and associated risk factors among presumptive pulmonary TB patients in the North Shewa Zone is limited. Assessing these parameters at Debre Berhan Comprehensive Specialized Hospital is essential for improving TB diagnosis and control.
objectiveThis study aimed to determine the prevalence of Mycobacterium tuberculosis using Gene Xpert and identify associated risk factors among presumptive pulmonary TB patients at Debre Berhan Comprehensive Specialized Hospital in 2025.
methodsAn institution-based cross-sectional study was conducted among 301 presumptive pulmonary TB patients. Participants were selected using a multistage sampling technique. Data were collected through structured and pretested questionnaires via face-to-face interviews. EpiData version 4.6 was used to enter the data; Stata version 16.1 was used to analyze the data. Univariable analysis were used to identify candidate variables (p ≤ 0.25) for multivariable logistic regression. Statistical significance was declared at p < 0.05 with 95% confidence intervals (CIs).
resultsOf 301 participants, 205 (68.1%) were male. The prevalence of pulmonary TB by Gene Xpert was 15.28% (95% CI: 11.63-19.82). Factors positively associated with TB positivity included close contact with known TB patients (AOR: 3.34; 95% CI: 1.22-9.09), HIV-positive status (AOR: 5.40; 95% CI: 1.86-15.61), farming occupation (AOR: 6.46; 95% CI: 5.12-15.60), and frequent cough (AOR: 8.90; 95% CI: 1.92-41.29).
conclusionThe prevalence of pulmonary TB among presumptive patients was high (15.28%). Targeted screening, early diagnosis, and interventions to improve environmental conditions are recommended to reduce TB transmission in this population. CLINICAL TRIAL NUMBER: Not applicable.
