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

The diagnosis of Incomplete Kawasaki disease (KD) is challenging. Approximately 20% of patients exhibit resistance to initial intravenous immunoglobulin (IVIG) therapy, termed IVIG-resistant KD, which is associated with a markedly increased risk of coronary artery aneurysms and long-term cardiovascular complications. We report a 4-month-old female infant who presented with 8 days of fever, bulging anterior fontanelle, elevated inflammatory markers, thrombocytosis, anemia, and leukocytosis. Echocardiography revealed left main coronary artery (LMCA) dilation (Z-score: 2.9), confirming incomplete KD with coronary involvement. Based on high-risk criteria augmented initial therapy with IVIG, prednisolone, and aspirin was initiated. Despite this, the fever persisted and coronary dilation progressed, confirming IVIG resistance. A second IVIG dose with intravenous methylprednisolone pulse therapy led to defervescence and echocardiographic improvement, with normalization of LMCA dimensions on follow-up. Early identification of high-risk incomplete KD, timely initiation of augmented therapy, and vigilant follow-up are critical in preventing coronary complications.
