Factors Influencing Tuberculosis Treatment Outcomes in Lalitpur District, Nepal: A Retrospective Cohort Study.
Article in Journal of epidemiology and global health, 2026. 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
purposeTuberculosis (TB) remains a major public health challenge in low- and middle-income countries, including Nepal. Understanding the factors associated with TB treatment outcomes is essential for improving disease control and patient management.
methodsA retrospective study was conducted using TB program data from Lalitpur District, Nepal. De-identified patient records were extracted from the Health Information Management System and the national e-TB register. Sociodemographic, behavioral, and clinical variables were analyzed. Descriptive statistics summarized patient characteristics, while Pearson's chi-square test assessed associations between variables and treatment outcomes. Multivariable logistic regression was used to identify predictors of treatment success.
resultsA total of 2,779 TB patients were included in the study. The overall treatment success rate was high, with most patients completing treatment successfully. Age, gender, and HIV status were significantly associated with treatment outcomes. Patients older than 60 years had higher odds of unsuccessful treatment compared with younger patients. Female patients showed higher odds of treatment success than males. HIV-positive patients had significantly poorer treatment outcomes compared with HIV-negative individuals. Other factors, including ethnicity, residence, smoking status, TB type, registration type, treatment category, DOTS delivery approach, and GeneXpert results, were not significantly associated with treatment success.
conclusionAge, gender, and HIV status were key predictors of TB treatment outcomes in Lalitpur District. Strengthening integrated TB-HIV care, improving follow-up among older patients, and enhancing treatment adherence among male patients may help improve treatment success rates. These findings provide evidence to support targeted TB control strategies and contribute to achieving the World Health Organization's End TB Strategy goals.
