Geographical Weighted Regression Analysis of Hotspots of Acute Respiratory Infection and Its Associated Factors among Children <5 Years in Ethiopia: A Spatial and Multilevel Analysis.
Article in Ethiopian journal of health sciences, 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
Background: The prevalence of acute respiratory infection (ARI) among children under five years of age varies across geographic regions, yet previous studies have not sufficiently addressed this variation in Ethiopia. Therefore, this study aimed to examine the geographic variation of ARI in Ethiopia using spatial analysis. Methods: A total of 10,417 children under five years were included in this study. Data analysis was conducted using STATA-17, ArcGIS 10.8, and SaTScan 9.6. Variables with a p-value <0.25 in the bi-variable analysis were included in the final model, and p-values <0.05 were considered statistically significant. Ordinary least squares (OLS) and geographically weighted regression (GWR) were employed to explore the spatial relationships between the outcome and determinant variables. The model with the lowest corrected Akaike Information Criterion (AICc) value was considered the best-fit model. Results: The prevalence of ARI among children under five in Ethiopia was 12.29% (95% CI = 11.68-12.94%). Most hotspot areas were located in Tigray, central Oromia, eastern SNNPR, and southern Amhara. In spatial analysis, significant predictors of hotspot areas included a higher proportion of rural women, children with diarrhea, Muslims, women with no education, low media exposure, and the poorest households. In the multilevel analysis, secondary maternal education, child age 48-59 months, recent diarrhea, and residence in Afar, Amhara, Benishangul, and SNNP were significantly associated with ARI. Conclusion: There is notable spatial variation in the prevalence of ARI in Ethiopia. Factors such as child age, recent diarrhea, maternal education, and region were significantly associated with this spatial variation. The government of Ethiopia should re-evaluate current ARI prevention strategies and implement geographically targeted interventions to reduce the burden of ARI.
