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

BCG scar reactivation is classically associated with Kawasaki disease but may also occur during immune activation caused by infections. We report a 26-month-old boy with laboratory-confirmed influenza B who developed transient erythema and swelling at a previous BCG vaccination scar without clinical features of Kawasaki disease or MIS-C. The scar reaction regressed with symptomatic treatment and oseltamivir as influenza symptoms improved. This case highlights that BCG scar reactivation is not specific to Kawasaki disease and should be interpreted within the full clinical context to avoid unnecessary investigations while maintaining appropriate follow-up.
