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
objectiveTo describe the incidence density of intussusception and its distribution characteristics across different ages, genders, and time periods among resident children aged 0-3 years in Jiangsu Province from 2018 to 2023, providing a scientific basis for health administrative departments in the region to formulate prevention and control strategies and measures for intussusception in children aged 0-3 years.
methodsA retrospective cohort study was conducted using data from the Jiangsu Regional Health Information Platform (RHIP). Resident children aged 0-3 years born between January 1, 2018, and December 31, 2023, were included. Suspected cases were identified by retrieving the International Statistical Classification of Diseases and Related Health Problems, 10 revision (ICD-10) code "K56.1" and semantically related keywords for "intussusception" from the original text using a regular expression matching algorithm. An incident case was defined as the first occurrence of the disease during the study period. Follow-up person-years were calculated using the exact person-time method. The Poisson distribution was applied to estimate the overall and subgroup incidence densities and their 95% confidence intervals (
resultsA birth cohort comprising 2 252 691 children aged 0-3 years was established, accumulating a total follow-up of 5 316 389.55 person-years. During the study period, 2 650 incident cases of intussusception were identified, including 1 600 boys (60.4%) and 1 050 girls (39.6%). The overall incidence density was 49.8 (95%
conclusionThis large retrospective cohort study based on the Jiangsu RHIP clarified the epidemiological characteristics of intussusception among local children aged 0-3 years from 2018 to 2023. Boys and children aged 8 months to 3 years were identified as high-risk populations for intussusception, with peak incidence occurring in summer and winter. These findings provide evidence-based support for health authorities to formulate targeted strategies for early surveillance, prevention, and healthcare resource allocation.
