Body Mass Index Trajectories Among Patients with Drug-Susceptible and Drug-Resistant Tuberculosis in Northwest Ethiopia.
Article in Infectious diseases and therapy, 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
introductionUnderstanding predictors of body mass index (BMI) trajectories in patients with drug-susceptible tuberculosis (DS-TB) and drug-resistant TB (DR-TB) is crucial for optimizing treatment strategies. This study examined BMI trajectories and predictors among patients with DS-TB and DR-TB in northwest Ethiopia.
methodsA retrospective cohort study was conducted using clinical data from patients attending TB clinics at four public hospitals in Northwest Ethiopia. We modelled BMI trajectories after TB treatment initiation using linear mixed models, with adjustments for potential confounders.
resultsA total of 988 patients were included in the analysis, comprising 569 with DS-TB and 419 with DR-TB. In the DS-TB cohort, male sex was associated with higher mean BMI (β = 0.39; 95% CI: 0.12-0.65), while baseline underweight status (β = -4.07; 95% CI: -4.33, -3.82) and baseline anaemia (β = -0.27; 95% CI: -0.53, -0.02) were associated with lower mean BMI across follow-up. In the DR-TB cohort, men had a higher mean BMI than women across the follow-up (β = 0.64; 95% CI: 0.16, 1.12). Although participants who were underweight at baseline (β = -3.62; 95% CI -4.06 to -3.18) or anaemic (β = -0.54; 95% CI: -0.98, -0.10) had a lower mean BMI across follow-up, they gained BMI more rapidly over time (time*underweight β = 0.04, 95% CI: 0.01, 0.07; time*anaemia β = 0.05, 95% CI: 0.01, 0.08).
conclusionEarly nutritional assessment and tailored nutritional support should be strengthened as part of routine TB care.
