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

BACKGROUND AND

aimsIn other forms of chronic liver disease, measurement of portal pressure is of prognostic value, but this has not yet been established in primary biliary cholangitis (PBC). The aim of the study is to determine the prognostic value of hepatic venous pressure gradient (HVPG) in relation to liver-related survival outcomes, as well as to the development of hepatic decompensation, oesophageal varices and variceal bleeding.

methodsBaseline HVPG and liver biopsies were obtained in 86 patients followed for 10 years in a controlled trial of colchicine treatment, and subsequently in a long-term observational cohort study for a further 30 years.

resultsThere were 49 Hepatic deaths in addition to 10 Liver Transplants (Hepatic death/transplant; n = 59). Some of these were associated with a significant variceal bleed within 3 months of death or transplant (Portal hypertension-associated death or transplant; n = 19). There were 63 deaths from all causes. During follow-up, oesophageal varices developed in 26 patients, whilst 17 bled from varices and 32 developed hepatic decompensation over a median follow-up of 18.1 years (1.9-28.5). Baseline HVPG was highly predictive of all 6 clinical outcomes and contributed significant predictive information additional to that provided by Mayo score and Ludwig stage.

conclusionMeasurement of baseline portal pressure is of significant prognostic value in primary biliary cholangitis.
