Gastrointestinal abnormalities as predictors of cardiovascular involvement in Kawasaki disease: a 5-year retrospective study.
Article in BMC pediatrics, 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
backgroundKawasaki disease (KD) is an acute, self-limited vasculitis in children that can lead to significant cardiovascular complications. Gastrointestinal manifestations and related laboratory abnormalities are common in KD, but their association with cardiovascular involvement remains incompletely understood. This study aimed to evaluate the relationship between gastrointestinal-related laboratory and imaging findings and echocardiographic outcomes in pediatric KD.
methodsWe conducted a retrospective study of 258 children with KD admitted from 2019 to 2024. Demographic, clinical, laboratory, and imaging data, including echocardiography and abdominal ultrasonography, were collected. Univariate and multivariate logistic regression analyses were performed to identify cardiovascular involvement, including coronary artery aneurysm, dilatation, brightness, and valvular abnormalities.
resultsAmong 258 patients (mean age 3.53 ± 2.69 years; 67.4% male), abnormal echocardiographic findings were observed in 70.7%. Coronary artery aneurysms and dilatation occurred in 9.8% and 9.4%, respectively. Abnormal abdominal sonography was detected in 21.3%. Multivariate analysis identified male sex, anemia, hypoalbuminemia, elevated alkaline phosphatase, elevated C-reactive protein, and prolonged partial thromboplastin time as independent associated factors of cardiovascular involvement in KD patients.
conclusionsGastrointestinal-related laboratory abnormalities are significantly associated with cardiovascular involvement in children with KD. Early recognition of high-risk patients, particularly males with anemia, hypoalbuminemia, elevated inflammatory markers, and abnormal liver enzymes, may assist in early risk stratification and intensified cardiac surveillance in the acute phase of KD.
