Quantification of pulmonary regurgitation and prediction of pulmonary valve replacement by echocardiography in patients with congenital heart defects in comparison to cardiac magnetic resonance imaging.
Article in The international journal of cardiovascular imaging, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
Pulmonary regurgitation (PR) is common in patients with congenital heart defects (CHD) and contributes to morbidity and mortality in the long-term. We investigated in this retrospective analysis whether readily accessible echocardiographic parameters are useful for quantification of PR and for predicting pulmonary valve replacement (PVR) in comparison to the gold-standard phase contrast (PC) flow measurements from cardiovascular magnetic resonance (CMR). Continuous wave (CW) Doppler and colour flow images in echocardiograms from 53 patients with CHD were analysed. Slope and jet-to-RVOT ratio correlated significantly with CMR-assessed regurgitation fraction (RF), whereas pressure half time (PHT) showed an inverse correlation. Patients with mild PR in CMR had significantly higher PHT, lower slope and jet-to-RVOT ratio than patients with moderate or severe regurgitation. The AUC regarding PR severity was 0.778 for PHT (95% CI, 0.649-0.907; P = 0.007 for CMR-RF ≤ 35%), 0.744 for slope (95% CI, 0.603-0.885; P = 0.017 for CMR-RF > 35%) and 0.652 for jet-to-RVOT ratio (95% CI, 0.473-0.860; P = 0.168 for CMR-RF > 35%). The optimal cut-off values calculated from ROC analysis were 95 ms for PHT and 4.9 m/s
