1 · What the graph read from it

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.

2 · The registry

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 systemic vasculitis of unknown origin. It represents one of the most important causes of acquired heart disease in the pediatric population. Coronary artery involvement is the most serious complication and may result in aneurysm formation and thrombosis. However, simultaneous involvement of all three major coronary arteries and giant aneurysm is rare and usually indicates severe disease. CASE PRESENTATION: This case report describes a 6-year-old boy with KD who developed progressive involvement of all three major coronary arteries despite standard treatment. The patient received intravenous immunoglobulin (IVIG) on the eighth day of illness, after which the fever resolved. However, follow-up imaging revealed a giant aneurysm of the left anterior descending (LAD) artery along with progressive dilation of the left circumflex (LCX) and right coronary arteries (RCA). During the clinical course, mural thrombosis developed within the LAD aneurysm, and the patient was readmitted for further management. Intensive medical therapy was initiated, including corticosteroids, cyclosporine, infliximab, anticoagulation, and antiplatelet agents. Coronary angiography demonstrated partial patency of the LAD with preserved distal run-off; therefore, surgical intervention was deferred. During follow-up, improvement of the aneurysms in the RCA and LCX was observed, whereas the LAD aneurysm and associated thrombosis persisted. Despite these findings, the patient remained clinically stable with preserved cardiac function and normal daily activities.

conclusionThis case report documented a rare occurrence of triple-vessel coronary involvement with a giant LAD aneurysm and thrombosis in KD. This study highlighted that, despite severe coronary abnormalities and resistance to standard treatment, favorable clinical outcomes may still be achieved with medical therapy and close long-term follow-up.
