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
backgroundTuberculosis (TB) is known to be a disease associated with underprivileged social conditions such as poverty, malnutrition, and overcrowding. Homeless individuals are at a higher risk of contracting TB due to factors such as substance misuse, alcohol disorder, smoking, and malnutrition. Recognizing this risk, the World Health Organization recommends TB screening in these vulnerable populations. As a result, this study aims to evaluate the prevalence of TB and its associated factors among people who experience homelessness living in Wolaita Zone Towns.
methodA cross-sectional study was conducted on 352 homeless individuals with presumed TB from May 1 to July 30, 2023. Data was collected using pre-tested structured questionnaires. The symptom was assessed using WHO guidelines. Sputum samples were screened for TB using GeneXpert MTB/RIF assay technique and those found to be positive were confirmed via the Lowenstein-Jensen(LJ) culture method by comparing equal numbers of positives and negatives. The data was analyzed using statistical software packages (SPSS) version 26. Logistic regression analysis was used to identify factors associated with TB and a P-value of less than 0.05 at a 95% confidence interval was considered statistically significant.
resultsThe prevalence of bacteriological confirmed TB among homeless individuals was 7.7% [95% CI: 4.8- 10.5] and rifampicin-resistant TB (RR-TB) was not detected. Multivariate logistic regression analysis revealed that smoking cigarettes[AOR = 7.673, 95% CI: 1.622,36.303], smoking benzene[AOR = 8.348, 95% CI: 2.061,33.813], chewing tobacco [AOR = 4.138, 95% CI: 1.249,13.709], duration of being homeless[AOR = 6.749, 95% CI: 1.914, 23.797], taking any medication currently [AOR = 4.686, 95% CI:1.216,18.064], BMI [AOR = 5.328, 95% CI: 1.663,17.070] and having HIV infection [AOR = 5.234, 95% CI: 1.558, 17.585] were significantly associated with the prevalence of PTB in people who experience homelessnesss.
conclusionsThis study indicates a higher prevalence of pulmonary TB (PTB) in homeless individuals compared to the general population. It is strongly recommended to implement targeted TB preventive and control measures and actively monitor for the diseases within those vulnerable population.
