Refractory Kawasaki Disease With a Coronary Artery Aneurysm in a Three-Month-Old Infant: Diagnostic Challenges and Rescue With Infliximab.
Article in Cureus, 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
Kawasaki disease (KD) is an acute systemic vasculitis and the leading cause of acquired heart disease in children. Diagnosis is particularly challenging in early infancy due to incomplete presentations. We describe a three-month-old infant with persistent fever, irritability, and lymphadenopathy who was initially treated for bacterial infection. By Day 7, the patient developed conjunctivitis, cracked lips, and pharyngeal congestion, meeting criteria for incomplete Kawasaki disease. Laboratory findings included leukocytosis, anemia, thrombocytosis, elevated C-reactive protein, and hypoalbuminemia. Initial echocardiography was normal; intravenous immunoglobulin (2 g/kg) with aspirin led to temporary improvement. Fever recurred, and repeat imaging revealed a right coronary artery aneurysm. Despite additional immunoglobulin and corticosteroids, the patient improved only after infliximab, with regression of coronary changes. This report emphasizes the diagnostic challenges of incomplete KD in early infancy, demonstrates practical application of the 2017 American Heart Association (AHA) diagnostic algorithm, and highlights the role of timely escalation to biologic therapy in refractory cases.
