1 · What the graph read from it

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.

2 · The registry

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

Introduction: The incidence of bacillary dysentery (BD) has declined significantly in China, yet BD outbreaks persist across multiple regions. This study describes the epidemiological characteristics of BD outbreaks nationwide and proposes targeted interventions for outbreak prevention and control. Methods: This study obtained BD outbreak data from the Public Health Emergency Event Surveillance System in China for descriptive epidemiological analysis and employed unconditional logistic regression to identify factors influencing outbreak magnitude. Results: During 2008-2024, China reported 176 BD outbreaks involving 9,854 cases and four deaths. The median attack rate and interquartile range for outbreaks were 5.99% (2.53%, 13.32%). Annual outbreak reports decreased throughout the study period, with no outbreaks documented in 2023 and 2024. Among all outbreaks, 75.6% occurred in rural areas, and 76.7% were reported in schools. Most outbreaks occurred during September or October (52.3%). Conclusions: In China, BD outbreak frequency has decreased substantially. September and October represent high-risk months, with schools serving as the primary outbreak setting during the back-to-school season. Strengthening BD prevention and control in educational institutions, with particular attention to water and food hygiene, remains essential for outbreak prevention.
