Contact tracing is associated with treatment success of index tuberculosis cases in Uganda.

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 determine the effect of contact tracing on the treatment outcomes of index tuberculosis (TB) cases in Uganda.
methodsWe evaluated TB cases registered at an urban public health facility in Uganda in 2015-2020. We extracted data from the unit's TB and contact tracing registers. Treatment outcomes were classified as cure, loss to follow-up, death and treatment failure. Treatment success was the sum of cure and treatment completion.
resultsAmong 778 TB cases, contact tracing was conducted for 455 (58.5%). Compared with cases without contract tracing (n=323), cases with contract tracing (n=455) had higher treatment success (92.5% vs 79.3%) and cure rates (57.1% vs 39.9%) and lower loss to follow-up (3.5% vs 9.3%), treatment failure (0.4% vs 1.6%) and death (3.5% vs 9.9%) (P<0.001). Contact tracing was associated with higher odds of treatment success (adjusted odds ratio (aOR) 3.00, 95% CI 1.92-4.70, P<0.001) and cure (aOR 3.11, 95% CI 1.97-4.90, P<0.001), and lower odds of loss to follow-up (aOR 0.33, (0.13-0.83), P=0.018) and death (aOR 0.38, (0.20-0.72), P=0.003).
conclusionTB contact tracing should be conducted consistently not only for the benefit of identifying new TB cases but also to promote treatment success of index cases.
