1 · What the graph read from it

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.

2 · The registry

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 current Organ Procurement Transplantation Network policy grants Model for End-Stage Liver Disease (MELD) exception points to patients with portopulmonary hypertension (POPH), but potentially important factors, such as severity of liver disease and pulmonary hypertension, are not included in the exception score, and may affect survival. The purpose of this study was to identify significant predictors of waitlist mortality in patients with POPH.

methodsWe performed a retrospective cohort study of patients in the Organ Procurement and Transplantation Network database with hemodynamics consistent with POPH (defined as mean pulmonary arterial pressure >25 mm Hg and pulmonary vascular resistance [PVR] ≥240 dynes·s·cm) who were approved for a POPH MELD exception between 2006 and 2014. Using a Cox proportional hazards model, we identified predictors of waitlist mortality (or removal for clinical deterioration).

resultsOne hundred ninety adults were included. Age (hazard ratio [HR], 1.04; 95% confidence interval [CI], 1.00-1.08; P = 0.0499), initial native MELD score (HR, 1.11; 95% CI, 1.05-1.17; P < 0.001), and initial PVR (HR, 1.12 per 100 dynes·s·cm; 95% CI, 1.02-1.23; P = 0.02) were the only significant univariate predictors of waitlist mortality and remained significant predictors in a multivariate model, which had a c-statistic of 0.71. PVR and mean pulmonary arterial pressure were not significant predictors of posttransplant mortality.

conclusionsBoth the severity of liver disease and POPH (as assessed by MELD and PVR, respectively) were significantly associated with waitlist, but not posttransplant, mortality in patients with approved MELD exceptions for POPH. Both factors should potentially be included in the POPH MELD exception score to more accurately reflect waitlist mortality risk.
