Household structures and exposure networks among people with multidrug-resistant TB in Namibia.
Article in IJTLD open, 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
backgroundMultidrug-resistant TB (MDR-TB) poses major challenges for TB control in high-TB-burden settings such as Namibia. In southern Africa, family and household structures are fluid, yet little is known about how MDR-TB interacts with these structures. We therefore explored family structures, household changes, and implications for transmission and care among people living with MDR-TB in Namibia.
methodsWe conducted a qualitative sub-study within the Hotspots, Hospitals and Households (H3TB) transmission of TB project. Between June 2021 and August 2023, 119 participants with MDR-TB were recruited from three regions of Namibia. In-depth interviews using participatory kinship, social network, and community mapping tools were conducted. Data were thematically analysed, with case studies illustrating household reconfigurations.
resultsWe identified 11 household structure patterns. Fourteen participants reported changes in household composition following MDR-TB diagnosis, driven by moving closer to health services, reorganising to optimise family care, reducing perceived exposure risks, and mitigating financial strain. These reconfigurations altered co-residence patterns and potential TB contact networks, with implications for household-based active case finding.
conclusionMDR-TB acts as a stressor prompting household reorganisation, reshaping networks of exposure, care, and support. Accounting for dynamic household contexts may strengthen TB contact tracing and patient support strategies.
