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
Background: Pulmonary regurgitation (PR) is common after tetralogy of Fallot (TOF) repair and closely associated with adverse outcomes. Transcatheter pulmonary valve replacement (TPVR) is a novel treatment for severe PR or mixed pulmonary stenosis (PS) and regurgitation. The aim of this study was to evaluate the changes in right ventricular (RV) function in patients after TPVR on two-dimensional (2D) and three-dimensional (3D) speckle tracking echocardiography and to identify the predictors of RV function and New York Heart Association (NYHA) functional class at 6 months after TPVR. Methods: Twenty-one patients who underwent TPVR were prospectively enrolled. 2D and 3D RV free wall longitudinal strain (2D-RVFWLS and 3D-RVFWLS) were obtained by 2D and 3D speckle tracking echocardiography, respectively, before TPVR and at 1 week and 6 months after TPVR. Results: The 2D-RVFWLS and 3D-RVFWLS at 1 week after TPVR were lower than those before TPVR and improved to the baseline levels at 6 months after TPVR (P<0.05). Preoperative 2D-RVFWLS and 3D-RVFWLS were independent predictors of RV function (β=0.415 and β=0.618; P<0.05) and NYHA functional class (β=0.636 and β=0.674; P<0.05) at 6 months after TPVR. In predicting RV function at 6 months after TPVR, the model with 3D-RVFWLS (R Conclusions: 2D-RVFWLS and 3D-RVFWLS decreased 1 week after TPVR and returned to the baseline levels at 6-month follow-up. Preoperative 2D-RVFWLS and 3D-RVFWLS are independent predictors of RV function and NYHA functional class at 6 months after TPVR.
