Factors influencing diagnostic discrepancy between preoperative transthoracic echocardiography and cardiovascular angiography in patent ductus arteriosus intervention: a multicenter retrospective study.
Article in Frontiers in pediatrics, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Introduction: Discrepancies between transthoracic echocardiography (TTE) and angiocardiography in assessing patent ductus arteriosus (PDA) dimensions may impact transcatheter closure outcomes. Methods: This multicenter retrospective study included 216 pediatric patients who underwent PDA closure, aiming to evaluate the prevalence and predictors of TTE-angiocardiography measurement discrepancy (defined as ≥0.5 mm difference). Results: 45.4% of patients exhibited significant discrepancy. Multivariate analysis identified tubular PDA morphology (OR = 2.71, Dsicussion: Nearly half of pediatric PDA cases show clinically relevant TTE-angiography discordance, particularly in patients with tubular morphology, small size, prematurity, or systemic abnormalities. These factors should prompt cautious interpretation of TTE and consideration of intraoperative angiographic confirmation to optimize device selection and procedural success.
