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
Objectives: Kawasaki disease (KD) is the leading cause of acquired childhood coronary aneurysms (CAA). Males are more affected than females, with lower survival from cardiac events and normalization rates. This study aimed to determine the association between biological sex and CAA risk and evaluate the association with baseline biochemical inflammatory markers by biological sex. Methods: This multicenter retrospective cohort study involved children ≤10 years old diagnosed with KD in five Canadian centres. Adjusted CAA risk differences between sexes were computed using binomial regression. Associations between inflammatory markers and CAA risk were analyzed using logistic regression with interaction terms between sex and inflammatory markers. Results: From 2004 to 2015, 1382 patients were diagnosed with KD and 812 (59%) were males. Median age, fever total duration, and fever duration at therapy initiation were similar between the sexes. The cumulative incidence of medium to large (Z ≥ 5) CAA was higher in males [70/812 (8.6%)] compared to females [19/570 (3.3%)], with an adjusted risk difference of 4.6 % (95% confidence interval [CI] 2.1 to 7.1). Large (Z > 10) aneurysms were more prevalent in males (adjusted risk difference of 3.3%, 95% CI 1.7 to 5.0). Most inflammatory markers were positively associated with CAA risk, but the association was not statistically different between sexes. Conclusion: Males with KD are at higher risk of developing CAA compared to females. The majority of patients were presumed to be prepubertal, suggesting that hormonal influences are unlikely to be a significant factor. Future KD research based on biological sex categorization should focus on patient risk stratification and long-term prognostic evaluation.
