Swedish Nationwide Study Found That Prematurity Was Associated With Kawasaki Disease.
Article in Acta paediatrica (Oslo, Norway : 1992), 2025. 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
aimOur aim was to identify perinatal and parental risk factors for Kawasaki disease (KD).
methodsSwedish patient and population registers were used to identify children diagnosed with KD and unaffected matched controls from 1987 to 2018. Logistic regression models were used to estimate odds ratios (OR) and 95% confidence intervals (CI) following exposure to perinatal and parental factors.
resultsWe identified 1645 cases (61% male) and 15 463 matched controls. The median age of KD diagnoses was 2.6 years. Preterm birth was significantly associated with increased odds of developing KD (OR 1.24, 95% CI 1.01-1.53), particularly for children diagnosed before 1 year of age (OR 1.82, 95% CI 1.15-2.86). Prenatal maternal smoking was also associated with diagnoses before 1 year of age and the risk was increased in males if their mothers were 35 years of age or older at the time of delivery. The risk was higher among children of Asian or African descent. Perinatal factors had a higher impact on the risk of KD in children with Asian parents.
conclusionPrematurity was significantly associated with an increased risk of developing KD. Other risks were prenatal maternal smoking, advanced maternal age, and being of Asian or African descent.
