Right ventricular-pulmonary arterial coupling may discriminate late right heart failure outcomes in left ventricular assist device recipients.
Article in JHLT open, 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
Right ventricular-pulmonary arterial (RV-PA) coupling more sensitively captures RV dysfunction and may identify those at risk for late right heart failure (LRHF). Fourteen left ventricular assist device patients underwent prospective RV pressure-volume loop assessment and outcome adjudication. RV-PA coupling was indexed by the ratio of pressure-volume-derived RV end-systolic elastance (Ees) to pulmonary arterial elastance (Ea). Receiver operating curves compared the ability of Ees/Ea with standard hemodynamic metrics to discriminate LRHF outcomes. Freedom from LRHF or cardiovascular-related death was compared between those above and below the Ees/Ea value with optimal sensitivity and specificity for LRHF (Ees/Ea = 0.36). Ees/Ea best discriminated LRHF outcomes (AUC 0.92;
