An assessment of video-observed treatment as an adherence support tool for patients with drug-resistant TB.
Article in IJTLD open, 2025. 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
backgroundIn 2017, WHO endorsed digital adherence technologies, including video-observed treatment (VOT), to support TB treatment adherence. In 2021, Eswatini implemented VOT to support adherence for drug-resistant TB (DR-TB) patients nationwide, although limited evidence exists regarding its feasibility and acceptability in low-resource settings.
methodsWe conducted 33 in-depth interviews with DR-TB patients and health care providers (HCPs), across all four regions of Eswatini to explore their experiences with VOT.
resultsThe findings indicated broad acceptance of VOT among both HCPs and patients. HCPs reported that VOT strengthened their connection with patients, facilitated adherence, and increased their confidence in treatment outcomes. While most patients found VOT user-friendly and appreciated the independence and privacy it offered, elderly patients faced challenges using smartphones, which sometimes resulted in poor-quality video submissions.
conclusionVOT is feasible and acceptable among HCPs and patients in Eswatini. Further research is needed to evaluate the impact of VOT on treatment outcomes in high-burden and low-resource settings to inform the scale-up of similar digital health interventions in comparable contexts. Strengthening digital infrastructure and providing tailored support for elderly patients could further enhance VOT effectiveness and equity.
