The impact of a bicuspid pulmonary valve in the aortic position after arterial switch for transposition of the great arteries on neoaortic root dimension and function: a propensity score matched analysis.

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
objectivesThis study investigated the effect of a bicuspid pulmonary valve on neoaortic root morphology, function, and the clinical outcomes of early survivors after the arterial switch operation using propensity score matching.
methodsFrom 1997 to 2018, a total of 442 patients underwent the arterial switch operation for transposition of the great arteries. After exclusion of patients who underwent a staged repair, were repaired beyond 1 year of age, died before discharge and who lacked echocardiographic data at discharge, propensity score matching was used for analysis.
resultsAmong 352 eligible patients, 18 patients (5.1%) had a bicuspid pulmonary valve. After propensity score matching (1:4), 15 patients with bicuspid valve (bicuspid group) and 60 patients with tricuspid valve (tricuspid group) were enrolled. The median follow-up duration was 9.9 years (4 months∼22.3 years). All-cause reoperation-free survival at 10 years was 93.3% in the bicuspid group and 87.0% in the tricuspid group (P = 0.839), and reoperation for neoaortic valve or root was required in 2 patients in the bicuspid group and 1 in the tricuspid group without intergroup difference. The z-score of the neoaortic annulus did not change in either group, although there was an increasing tendency in the z-score of the neoaortic sinus without intergroup difference (P = 0.690). Deterioration in neoaortic valve function was more prominent in the bicuspid group (p = 0.028).
conclusionsThe neoaortic sinus might outgrow the norm regardless of the number of neoaortic valve cusps, whereas the neoaortic annulus remained unchanged. Deterioration of valve function was more prominent in the bicuspid group, which suggests that a bicuspid valve might play a significant role in deterioration of neoaortic valve function, without an additional effect on root pathology.
