Spatial, temporal, and spatiotemporal analysis of pertussis in Shapingba District, China, 2014-2024.
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
backgroundPertussis has resurged globally, with a sharp increase in 2024 posing serious risks to children health. This study analyzed the epidemiological and spatiotemporal patterns of pertussis in Shapingba District, China, from January 1, 2014 to December 31, 2024, to identify high-risk groups and areas for targeted prevention.
methodsReported pertussis cases were obtained from China Information System for Disease Control and Prevention. Descriptive statistics, spatial autocorrelation (GeoDa), and spatiotemporal scan analysis (SaTScan) were used. ArcMap was applied for visualization.
resultsA total of 2,899 cases were reported, with an average annual incidence of 18.42 per 100,000, peaking at 157.26 in 2024. An age shift was observed: before 2021, infants under 1 year had the highest incidence; from 2021, cases rose among children aged 6–13 years. Spatial clusters were identified in 2015, 2016, 2022, and 2024, with high-risk areas shifting west and southeast over time. Eleven significant clusters occurred between March and August 2024.
conclusionPertussis in Shapingba District showed increasing incidence and shifting age and spatial patterns. Enhanced surveillance, optimized immunization schedules, and targeted interventions are urgently needed.
