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

Introduction: The blood urea nitrogen to serum albumin ratio (BAR) may serve as a prognostic marker. This study evaluated its association with clinical outcomes in patients with acute pancreatitis (AP). Material and methods: We performed a retrospective cohort analysis using data from the MIMIC-IV 2.2 database, including 650 patients diagnosed with AP. The primary outcomes were 90-day and 365-day mortality. Cox proportional hazards models assessed the relationship between BAR and mortality. Restricted cubic spline (RCS) analysis examined the non-linear relationship. Results: Among the 650 patients, the mortality rates at 90 days and 365 days were 21.2% and 26.2%, respectively. Higher BAR levels correlated with increased 90-day and 365-day mortality ( Conclusions: Elevated BAR is significantly associated with increased mortality in AP patients, indicating its potential as a valuable prognostic marker in critical care settings.
