Temporal trends and spatial heterogeneity of sanitation facilities in Ethiopia: evidence from the 2005-2019 Demographic and Health Surveys.
Article in BMJ open, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundThe main aim of sanitation is to prevent human contact with faecal pathogens to decrease occurrences of diseases. However, no region in the world is on the right track to accomplish Sustainable Development Goal (SDG) 6.2 for universal access to sanitation. Sub-Saharan Africa, including Ethiopia, is significantly behind in meeting the 2030 SDG 6.2 targets. Hence, this study focused on the spatial and temporal analysis of sanitation in Ethiopia based on four demographic health surveys.
designThis research was undertaken among households in Ethiopia based on a weighted sample size. Variables with a p<0.2 in bivariable analysis were incorporated into the multivariable analysis. Subsequently, a 95% CI and a p<0.05 were used to assess the statistical significance of the final model. Global and local indicators of spatial correlation were done. Statistical analyses were performed by using STATA V.17 and ArcGIS V.10.7 software.
resultsThis study includes data from 13 721 households in the 2005 Ethiopian Demographic and Health Survey (EDHS), 16 702 households in the 2011 EDHS, 16 650 households in the 2016 EDHS and 8663 households in the 2019 EDHS. The prevalence of improved sanitation facilities in Ethiopia was 20.46%, 25.61%, 25.86% and 27.45% based on EDHS 2005, 2011, 2016 and 2019, respectively. Global Moran's I spatial autocorrelations, hotspots and spatial interpolation analysis indicated the inequality of improved sanitation facilities. Educational status of primary (adjusted OR, AOR 2.43, 95% CI 2.00, 2.95), secondary (AOR 2.02, 95% CI 1.61, 2.54) and higher (AOR 4.12, 95% CI 3.35, 7.54), watching television (AOR 5.49, 95% CI 4.37, 6.89), urban areas (AOR 9.08, 95% CI 6.69, 12.33) and region were factors statistically associated with sanitation facilities.
conclusionThe overall finding of this study concludes a very slow increment in sanitation facilities over time and the presence of geographical heterogeneity in Ethiopia. Educational status, watching television, wealth index, community-level education, type of residence and region were factors statistically associated with sanitation facilities.
