Armed conflict intensity and inequalities in tuberculosis outcomes in Colombia municipalities, 2008-2019.
Article in BMJ 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
backgroundColombia's prolonged armed conflict has significantly impacted public health. This study constructs a municipal-level armed conflict intensity index for Colombia (2008-2019) and assess inequalities in tuberculosis (TB) case notifications, mortality and fatality rates across levels of conflict intensity.
methodsThis retrospective ecological study included 1122 Colombian municipalities from 2008 to 2019. Data on conflict were obtained from the National Observatory of Historical Memory, and TB mortality and morbidity data were sourced from the National Public Health Surveillance System. A Conflict Intensity Index (CII), summarising intensity of armed conflict at the municipal level by ranking municipalities, was estimated using principal component analysis (PCA) to analyse two time periods (2008-2013 and 2014-2019). Age-adjusted and sex-adjusted TB rates were calculated, and disparities were assessed using the Relative Index of Inequality (RII) and Slope Index of Inequality.
resultsAreas with higher conflict intensity showed a greater TB burden in both mortality and case notifications. Although TB notification rates decreased by 16% nationally over the study period, this reduction was not evenly distributed, and inequalities persisted, with TB notifications and mortality concentrated in high-conflict areas. Children under 1 year faced the highest inequities, with an RII of 1.39, indicating a 39% higher likelihood of TB in these areas. Women also exhibited sustained disparities, and high-conflict municipalities continued to have elevated mortality rates despite a national reduction of 9%.
conclusionThe impact of armed conflict on TB was not uniform across all settings. Persistent inequalities affecting young children and women in high-conflict municipalities highlight the need for territorially differentiated TB control strategies. Integrating conflict-sensitive approaches into TB surveillance, prevention and care is essential to reduce inequities and translate epidemiological evidence into effective public health action.
