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 &

aimsThe impact of proton pump inhibitory (PPI) medications on adverse outcomes in cirrhosis remains controversial. We aimed to evaluate the association between PPI exposure and all-cause mortality, infection, and decompensation in a large national cohort.

methodsThis was a retrospective study of patients with cirrhosis in the Veterans Health Administration. PPI exposure was classified as a time-updating variable from the index time of the cirrhosis diagnosis. Inverse probability treatment weighting-adjusted Cox regression was performed with additional adjustment for key time-varying covariates, including cardiovascular comorbidities, gastrointestinal bleeding (GIB), and statin exposure.

resultsThe study included 76,251 patients, 23,628 of whom were on a PPI at baseline. In adjusted models, binary (yes/no) PPI exposure was associated with reduced hazard of all-cause mortality in patients with hospitalization for GIB (hazard ratio [HR], 0.88; 95% confidence interval [CI], 0.84-0.91; P < .001) but had no significant association in all others (HR, 0.99; 95% CI, 0.97-1.02; P = .58). However, cumulative PPI exposure was associated with increased mortality in patients without hospitalization for GIB (HR, 1.07 per 320 mg-months [omeprazole equivalents]; 95% CI, 1.06-1.08; P < .001). PPI exposure was significantly associated with severe infection (HR, 1.21; 95% CI, 1.18-1.24; P < .001) and decompensation (HR, 1.64; 95% CI, 1.61-1.68; P < .001). In a cause-specific mortality analysis, PPI exposure was associated with increased liver-related mortality (HR, 1.23; 95% CI, 1.19-1.28) but with decreased nonliver-related mortality (HR, 0.88; 95% CI, 0.85-0.91).

conclusionsPPI exposure is associated with increased risk of infection and decompensation in cirrhosis, which may mediate liver-related mortality. However, PPI use was associated with reduced all-cause mortality in those with prior GIB, suggesting benefit in the presence of an appropriate indication.
