Epidemiological analysis of a cholera outbreak in pastoral communities in the Somali region of Ethiopia.
Article in BMC 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
backgroundCholera is an acute diarrhea disease caused by infection of the intestine with the toxigenic bacterium Vibrio cholerae serogroup O1 or O139. It is a waterborne disease of global health importance with an estimated 3 to 5 million cases and over 100,000 deaths annually.
methodsOur key objective was to analyze the epidemiology of a cholera outbreak in the Somali region of Ethiopia, which took place in 2017, using an electronic surveillance cholera database. We investigated 7 cholera-affected-districts. In total, 4115 cases of cholera were reported, of which 3846 (93.5%) records were eligible.
resultsThree thousand eight hundred forty six cases and 112 deaths from 11 Cholera Treatment Centres (CTC) were reported, with attack risk (AR) of 103 per 10,000 populations, and a case fatality rate (CFR) of 2.95 %. The CFR was 3.1 in females and 2.8 in males. People with travel history to a cholera affected area were five times more likely to die from cholera (OR 5.00; 95% CI 3.23-7.87). People with severe dehydration were seven times more likely to die (OR 7.80; 95%CI 2.44-47.60). The age-specific CFR was highest (4.9%) in the 2-4 years’ age group, and lowest (1.7%) in the 15-44 age range.
conclusionsPastoral communities ought to be provided access to clean and safe drinkable water. There must be availability of anti-cholera vaccines to tackle the burden of the disease, for example, the OCV recommended by the Global Task Force on Cholera Control.
