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
Introduction: In Uganda, people with multi-drug resistant and rifampicin-resistant tuberculosis (MDR/RR-TB) have been treated with a bedaquiline-based regimen since 2020. Still, their treatment outcomes have not been rigorously studied. We describe the treatment outcomes of people with MDR/RR-TB treated with a bedaquiline-based regimen and analyze the factors associated with their treatment success at three referral hospitals in Uganda. Method and materials: We retrospectively reviewed medical records for people with MDR/RR-TB treated with a bedaquiline-based regimen between January 2020 and December 2021 at 3 referral hospitals. Treatment success was defined as cure or treatment completion on a binary scale at the end of the MDR/RR-TB treatment. Factors independently associated with treatment success were analyzed using the modified Poisson regression analysis with robust standard errors, reported as risk ratio (RR) and 95% confidence interval (CI). Analyses were performed at a 5% level of statistical significance. Results: Of 71 participants aged ≥ 15 years, 13 (18.3 %) completed treatment, 46 (64.8) were cured, 8 (11.3) died, and 4 were lost to follow-up. Overall, 59 (83.1) were successfully treated. Current alcohol consumption (adjusted RR [aRR] 0. 78, 95 % CI 0.60-0. 99) and high aspartate aminotransferase levels (aRR 0.77, 95 % CI 0.60-0.98) were associated with a lower treatment success. Conclusion: The treatment success among people with MDR/RR-TB on a bedaquiline-based regimen was relatively high. High AST levels and alcohol consumption are associated with a lower treatment success. There is a need to strengthen psychosocial support regarding the harmful effects of alcohol consumption and its interaction with drugs, including routine monitoring of liver function to enhance the TB treatment success.Our study is the first to describe treatment success among people with MDR/RR-TB in three large hospitals in Uganda, this provides a good picture of treatment success among people with MDR/RR-TB on bedaquiline-based regimens in the country. The weaknesses are the smaller sample size, we analyzed data spanning a relatively shorter period, and alcohol use was measured by self-reporting, this might have underestimated its association with treatment success.
