Determinants of unfavourable treatment outcomes of drug-resistant tuberculosis cases in Malaysia: a case-control study.
Article in BMJ open, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
objectivesThe emergence of drug-resistant tuberculosis (DR-TB) complicates TB management and poses significant challenges to achieve favourable treatment outcomes. Treating DR-TB is more complex and costly, requiring extended treatment durations and consideration of drug toxicity and side effects. This study aims to identify the determinants of unfavourable treatment outcomes among DR-TB patients in Malaysia.
designRetrospective case-control study.
settingSecondary data from the National Tuberculosis Registry (NTBR) across two states in Malaysia.
participantsAll reported DR-TB cases in the NTBR between 2016 and 2020 from Selangor and Wilayah Persekutuan Kuala Lumpur, Malaysia. Cases still undergoing treatment at the time of analysis were excluded. A total of 403 cases were analysed, with 181 (44.9%) experiencing unfavourable treatment outcomes and 222 (55.1%) having favourable treatment outcomes. The case group consists of individuals with DR-TB who experienced unfavourable treatment outcomes, while the control group comprises individuals with DR-TB who achieved favourable treatment outcomes. OUTCOME MEASURES: Unfavourable treatment outcomes, defined as death, treatment failure or loss to follow-up, were assessed. Predictors of these outcomes were identified through multiple logistic regression analysis.
resultsSignificant determinants of unfavourable treatment outcomes included being male (adjusted OR (aOR) 2.38, 95% CI 1.44 to 3.94), being single or divorced (aOR 1.61, 95% CI 1.03 to 2.49), having no formal education (aOR 3.09, 95% CI 1.49 to 6.41), people living with HIV (aOR 2.87, 95% CI 1.40 to 5.87) and having DR-TB categorised as rifampicin-resistant tuberculosis (aOR 3.34, 95% CI 1.90 to 5.86) or multidrug-resistant/pre-extensively drug-resistant/extensively drug-resistant-TB (aOR 2.57, 95% CI 1.52 to 4.33).
conclusionThe findings reveal a high proportion of DR-TB cases with unfavourable treatment outcomes and identify their key determinants. Targeted interventions addressing these factors are essential to improve treatment outcomes.
