Clean Energy and Health Expenditure in an African Setting: A Socioeconomic Analysis of Household Costs and Willingness to Pay.

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
Background: Climate vulnerability in sub-Saharan Africa, including Nigeria, has heightened concern about household energy transitions and associated health and economic impacts. Despite clean fuel initiatives, uncertainty remains regarding household expenditure patterns, health expenditures, and socioeconomic drivers of adoption. Objectives: To examine (1) household cooking-energy and respiratory healthcare expenditures, (2) descriptive expenditure ratios comparing energy costs with respiratory healthcare spending including benefits of transitioning to cleaner energy solutions, and (3) the socioeconomic determinants that influence households' willingness to transition to cleaner cooking practices. Methods: A cross-sectional household survey was conducted in Alimosho (Lagos State) and Ado-Odo Ota (Ogun State) in southwest Nigeria. Using a multistage cluster sampling approach, 292 respondents from 200 households were surveyed on cooking-energy expenditures, respiratory healthcare costs, and willingness to adopt clean fuels. Expenditure patterns were compared descriptively, and a model-based cost-utility analysis was performed to estimate the incremental cost-effectiveness ratio in US dollars per disability-adjusted life-years (DALYs) averted. A multivariable logistic regression model was used to examine socioeconomic predictors of willingness to adopt clean cooking. Results: Clean-fuel (liquefied petroleum gas or electricity) households reported higher annual cooking-energy expenditures than polluting-fuel households (US Conclusions: Expenditure differences by fuel type likely reflect underlying socioeconomic conditions and variations in healthcare access, rather than causal effects of fuel choice. The model-based cost-utility analysis suggests that clean cooking could be cost-saving or highly cost-effective under plausible assumptions. Policies that address affordability and supply constraints, alongside stronger longitudinal evidence, are needed to support equitable and sustained clean-cooking transitions in Nigeria and across sub-Saharan Africa.
