Determinants of health-related quality of life in drug-susceptible tuberculosis patients in Ghana: a prospective observational study.

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
Background: Tuberculosis (TB) affects patients' quality of life due to symptoms and social stigma, especially in low-income settings like Ghana. However, data on factors influencing health-related quality of life (HRQOL) in such environments are limited. Identifying these factors is essential for improving treatment outcomes through holistic care. Objective: This study determined the impact of sociodemographic and clinical factors on HRQOL at treatment initiation, and monitored changes until the end of treatment. Design: Prospective observational study. Methods: A cohort of 378 newly diagnosed patients with drug-susceptible TB (mean age: 45.3 ± 15.1 years) was followed across eight hospitals in the Ashanti and Eastern regions of Ghana. Patients received first-line antitubercular treatment, and HRQOL was assessed at baseline, month 2, and month 6 using an interviewer-administered SF-12v2 questionnaire. Associations between HRQOL and sociodemographic or clinical factors were examined using Chi-square or Fisher's exact tests, while logistic regression was used to estimate crude and adjusted odds ratios ( Results: At baseline, 78.8% of participants had impaired physical HRQOL, and 25.7% were at risk of depression. At treatment completion, physical HRQOL impairment remained high (59.5%), with 15.0% still at risk of depression. Only 44.7% showed clinically significant improvement in physical HRQOL, while 39.8% improved in mental HRQOL. Employment, HIV-positive status, and alcohol use were associated with poorer mental HRQOL. Extrapulmonary TB patients demonstrated better physical HRQOL at both the beginning and end of treatment but exhibited poorer mental HRQOL at treatment completion. Widowed participants improved mentally despite poorer baseline health, while married individuals had better physical HRQOL. Higher education correlated with better baseline mental health but lower odds of significant HRQOL improvement. Conclusion: Sociodemographic and clinical factors significantly influenced HRQOL in drug-susceptible TB patients after 6 months of treatment. These findings underscore the importance of targeted mental health support during and after treatment to improve patient well-being.
