Analysis of the epidemiological characteristics of foodborne botulism in Xinjiang, China from 2016 to 2024.
Article in BMC infectious diseases, 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
backgroundThis study systematically analyzes the epidemiological characteristics of foodborne botulism in Xinjiang from 2016 to 2024.
methodsData were collected from reports across Xinjiang, with all events confirmed through epidemiological investigation, laboratory testing, and food hygiene surveys. Descriptive statistical analysis was performed using R Studio (version 4.3.1).
resultsA total of 79 foodborne botulism events (including outbreaks and sporadic cases) were reported, including 52 laboratory-confirmed and 27 clinically diagnosed events, involving 103 confirmed cases and 228 exposed individuals. The attack rate was 45.2%, with a case-fatality rate of 1.94%. Homemade foods were the primary risk factor, particularly among middle-aged and elderly populations. Type A botulinum neurotoxin (BoNT) was dominant. Most events occurred in January and May, with the highest number of cases in Urumqi City and Ili Prefecture.
conclusionThe study reveals a unique etiological pattern in Xinjiang, characterized by the absolute dominance of a specific toxin serotype. While traditional homemade foods remain the major risk, emerging threats from commercially distributed foods are becoming significant, underscoring the need for continuously strengthened risk response capabilities.
