Right Ventricular Function Score by Echocardiography for Predicting Outcomes After Heart Transplantation.

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
backgroundThe impaired right ventricular (RV) function may occur after heart transplantation (HT). This study aimed to develop a straightforward RV function score (RVFS) using echocardiography to predict adverse clinical events in a large cohort of subjects after HT.
methodsA total of 357 consecutive patients post HT who underwent echocardiography at our single institution were retrospectively included. RV systolic function was evaluated by echocardiography. A multivariate Cox regression analysis was performed to identify the independent predictors of RV function for adverse clinical events.
resultsDuring a median follow-up of 39 months from the date of the echocardiography, a composite of adverse events that included death and major adverse cardiac events occurred in 51 patients. The multivariate Cox analysis revealed that RV fractional area change, tricuspid annular plane systolic excursion, and RV free wall longitudinal strain were independent predictors of outcomes after HT. The RVFS was constructed based on these 3 parameters, assigning a value of 1 when a predictor was below its cutoff value from receiver operating characteristic curves and 0 when above. The RVFS outperformed separate RV function parameters in predicting outcomes (area under the curves: 0.84 versus 0.64-0.78,
conclusionsThe RVFS, a readily obtainable echo score that combines multiple RV function parameters, exhibits incremental value and significant potential as a robust predictor for adverse outcomes in clinically stable patients after HT.
