Unexpected Fetal Supraventricular Tachycardia Temporally Associated With Maternal Antihistamine Use: A Case Report.

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
Fetal supraventricular tachycardia (SVT) represents the most common cause of sustained fetal tachyarrhythmia and may result in significant hemodynamic compromise when persistent. Data regarding the cardiovascular effects of maternal antihistamine use during pregnancy remain limited. We report a near-term fetus with sustained SVT temporally associated with maternal ingestion of cetirizine and an antihistamine-decongestant combination for the treatment of allergic rhinitis. Owing to the persistence of the tachyarrhythmia during hospitalization, transplacental antiarrhythmic therapy with flecainide was initiated. After 48 h of treatment, successful rhythm control was achieved. Concurrent use of cetirizine and an antihistamine decongestant in a single dose during pregnancy resulted in sustained SVT in the fetus, necessitating treatment. Therefore, the use of cetirizine in the third trimester and antihistamine decongestants throughout pregnancy requires further investigation.
