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

backgroundImproved renal function (IRF) observed in acute heart failure (AHF) is associated with poor prognosis. Since IRF is linked to renal congestion resulting from inadequate decongestion, predicting IRF could enhance management strategies. The Fibrosis-4 (Fib-4) index, originally developed as a marker for liver fibrosis, correlates with hepatic congestion, which is associated with renal congestion, making it a potential predictor of IRF. This study aims to investigate whether the Fib-4 index can predict IRF in patients with AHF and preserved ejection fraction (AHFpEF).

methodsWe analyzed 389 patients hospitalized for AHF between April 2004 and March 2022 at Yamanashi University Hospital. All-cause mortality was monitored for 1 year. IRF was defined as a ≥ 20% increase in the estimated glomerular filtration rate (eGFR) compared to admission levels. Preserved ejection fraction was defined as an ejection fraction ≥ 40%.

resultsIRF was observed in approximately 21% of patients with AHFpEF. Kaplan-Meier analysis showed that patients with IRF had higher mortality rates than those without IRF (p = 0.03, log-rank test). Multivariable analysis for IRF revealed that the eGFR, albumin level, and a Fib-4 index ≥ 3.24 (determined by receiver-operating characteristic curve) on admission were independent predictors of IRF in patients with AHFpEF.

conclusionIRF in patients with AHFpEF is associated with poor prognosis. A higher Fib-4 index at admission in AHFpEF can serve as a predictor of IRF.
