Recoupling of right and left ventricle pump function after surgical ventricle restoration: a cardiac magnetic resonance study.

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
To evaluate biventricular pump function after surgical ventricle restoration (SVR) using cardiac magnetic resonance (CMR). We retrospectively studied 39 patients who performed 1.5-T CMR before/after SVR acquiring short-axis ECG-gated cine sequences. End-diastolic, end-systolic, and stroke volume indexed to body surface area (EDVI, ESVI, and SVI), ejection fraction (EF), and their modification after SVR (∆) were obtained for right ventricle (RV) and left ventricle (LV). Wilcoxon signed rank test and Spearman correlation coefficient were used; EF reproducibility was estimated. Median LVEF increased from 24% [interquartile range (IQR) 19-31%] before SVR to 34% (IQR 29-43%) after SVR (P < 0.001). Median RVEF remained unchanged from 58% (IQR 48-66%) before SVR to 57% (IR 46-64%) after SVR (P = 0.743). The correlation between LVEF and RVEF was not significant before SVR (r = 0.182; P = 0.266) but significant after SVR (r = 0.445; P = 0.005). The ∆RVEF was positively correlated with ∆LVEF (r = 0.558; P < 0.001). ∆RVSVI was positively correlated with ∆LVSVI (r = 0.502; P = 0.001). LVEF reproducibility before SVR was 97% for both intra- and inter-reader reproducibility; RVEF reproducibility was 96 and 93%, respectively. SVR improved LV function without apparent impact on RV function. After SVR the two ventricles showed a functional recoupling. Reproducibility of CMR EF was excellent for both ventricles.
