Risk factors for tuberculosis treatment outcomes: a statistical learning-based exploration using the SINAN database with incomplete observations.
Article in BMC medical informatics and decision making, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundUnderstanding early predictors of treatment outcomes allows better outcome prediction and resource allocation for efficient tuberculosis (TB) management.
objectivesThis study aimed to predict treatment outcomes of TB patients from a real-world population-wide health record dataset with a significant rate of incomplete observations. In addition, potential risk factors associated with death during TB treatment were investigated.
methodsWe exploited the upweighting approach and multiple imputation analysis (MIA) to address the extreme imbalance in responses and missing data. Three algorithms were employed for TB treatment outcome prediction, including logistic regression (LOGIT), random forest, and stochastic gradient boosting. The three models exhibited similar performance in predicting the treatment outcomes. Moreover, an interpretation of LOGIT was conducted, adjusted odds ratios (aORs) were computed, and the interpretation results were compared between MIA and complete case analysis (CCA).
resultsMIA was an appropriate method for coping with missing data. In addition, compared to CCA, the interpretation results of the MIA-derived LOGIT showed more statistically significant covariates associated with TB treatment outcomes. In MIA, factors such as TB clinical form involving both pulmonary TB and extrapulmonary TB [aOR = 3.077, 95% confidence interval (CI) = 2.994-3.163], retreatment after abandonment (aOR = 2.272, 95% CI = 2.209-2.338), and the absence of isoniazid (aOR = 2.072, 95% CI = 1.892-2.269) or rifampicin (aOR = 1.968, 95% CI = 1.746-2.218) in the treatment regimen were associated with increased odds of death.
conclusionIn conclusion, our results shed light on the potential risk factors for death during TB treatment and suggest the use of simple yet interpretable LOGIT for the prediction of TB treatment outcomes.
