Heat Adaptation Benefits for Vulnerable groups In Africa (HABVIA): a study protocol for a controlled clinical heat adaptation trial.
Article in BMC public health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundTemperatures across Africa are expected to rise at up to twice the rate of mean global temperatures, posing significant health threats to vulnerable communities. Prolonged exposure to high day- and night-time temperatures has been implicated in a myriad of adverse health outcomes. The built environment and inadequate housing can exacerbate these consequences, prompting the need to evaluate heat adaptation interventions as a sustainable adaptation strategy for low-income and informal settlement dwellers. The Heat Adaptation Benefits for Vulnerable groups In Africa (HABVIA) study aims to assess the impact of passive cooling interventions in homes on several key physiologic and mental health outcomes, as well as building internal thermal conditions.
methodsHABVIA is a 3-year prospective controlled study to identify, implement and assess heat adaptation solutions in four low-income communities in one urban and one rural site in Ghana and South Africa, respectively. In each site, N=240 participants (N=60 per site) will be assigned to intervention or control groups. The intervention is focused on lowering the nighttime temperature of the home environment. Health and biometric data will be collected through a combination of physiological measurements, questionnaires, and biochemical measures taken at 3 time points during the hot season. Clinical outcomes include objective sleep behaviour, core body temperature, physical activity, blood pressure, blood glucose, anthropometrics, and body composition. Indoor and outdoor environmental data will be collected continuously using fixed indoor sensors and automatic weather stations. Housing and community characteristics, and socio-economic information will be collected. Quantitative comparisons will be made between intervention and control conditions using generalised linear mixed models. Qualitative data from consultive workshops will be used to assess the acceptability and feasibility of the adaptations. DISCUSSION: Robust evaluation of the environmental and health outcomes of heat adaptations are limited for Africa, despite high climate vulnerability. HABVIA will address some of these gaps by assessing low-cost passive cooling interventions to promote heat resilience and improve health outcomes, providing real-world evidence for the feasibility of readily implementable and scalable adaptations in local contexts.
