Temporal Trends in Portopulmonary Hypertension Model for End-stage Liver Disease Exceptions and Outcomes.
Article in Transplantation direct, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers, 1 of them a synthesis that pooled 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.
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
Model for end-stage liver disease (MELD) exception criteria for portopulmonary hypertension (POPH) were created to prioritize patients for liver transplant before POPH progression. Little is known about trends in POPH exception frequency, disease severity, pulmonary hypertension treatment patterns, or outcomes since the POPH MELD exception began. Methods: Using data from the Organ Procurement and Transplantation Network database, we describe the frequency of POPH MELD exceptions between 2006 and 2019, compare baseline patient characteristics, and characterize trends in liver disease and POPH severity' as well as POPH treatment and outcomes' over time. To facilitate comparison, we divided this 14-y period into 3 "eras" (2006-2010, 2011-2015, and 2016-2019). Results: Between 2006 and 2019, 504 unique POPH MELD exceptions were granted. Both liver disease severity and patient age have increased over time ( Conclusions: In conclusion, 504 patients have received POPH MELD exceptions between 2006 and 2019. Since 2010, nearly all patients granted POPH MELD exceptions have met hemodynamic criteria for POPH. Over time, there has been a trend toward older age and higher MELD scores with significant changes in pulmonary arterial hypertension treatment patterns and an improvement in posttreatment hemodynamics without major change in outcomes.
