Acceptability and usability of home-based HIV and blood glucose self-testing and home-based blood pressure measurement in Kenya, South Africa, and Zambia.
Article in PLOS global public 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
Home-based self-testing may improve individual health outcomes and public health programs by lowering barriers associated with clinic-based testing in low- and middle-income countries (LMICs). We assessed the acceptability and usability of conducting home-based self-testing for HIV and blood glucose and home-based researcher-conducted testing for blood pressure in sub-Saharan Africa. We enrolled participants (≥15 years old) from households in peri-urban and rural communities of Kenya, South Africa, and Zambia. Participants opted in to self-directed testing for HIV and blood glucose and had their blood pressure measured by a research team member. Our primary measures included HIV status and testing history, HIV and blood glucose test results, blood pressure, self-reported usability and acceptability of self-testing, and participant preferences for future self-testing. Among the 526 participants from 100 households enrolled per country, the average age was 41 years and 63% were female. Overall, 16% of participants reported living with HIV. Over half of participants (52%) had last tested for HIV > 12 months ago or had never tested for HIV, and 8% of participants were unsure of their HIV status. Among participants who self-tested, 2% (n = 6/330) tested positive for HIV and 4% (n = 18/469) had high blood glucose, while 26% (n = 131/502) had high blood pressure measured by the study team. Only 14% of study participants reported previous self-testing. Most (>90%) participants who self-tested rated all procedures for HIV and blood glucose tests as either "very easy" or "fairly easy" to use. Most participants (87%, n = 458/526) preferred home-based testing. Home-based self-testing for HIV and blood glucose and home-based blood pressure measurement were acceptable, usable and preferred in peri-urban and rural areas of Kenya and South Africa; findings from Zambia suggest promise for home-based testing but were limited by staff-administered HIV tests. Self-testing has the potential to expand and accelerate access to healthcare delivery in LMICs.
