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: Hypochloremia is increasingly recognized as a marker of neurohormonal activation and adverse prognosis in acute decompensated heart failure (ADHF). However, the magnitude and consistency of its association with short-term mortality remain uncertain. This meta-analysis aimed to evaluate the relationship between admission serum chloride levels and in-hospital mortality among patients hospitalized with ADHF. Methods: PubMed, Embase, and Web of Science were searched for cohort studies reporting the association between admission serum chloride levels and in-hospital mortality in ADHF. Pooled risk ratios (RRs) with 95% confidence intervals (CIs) were calculated using a random-effects model accounting for the possible influence of heterogeneity. Results: Seven studies comprising eight independent cohorts and 17,239 ADHF patients were included. Overall, 2,422 (14.0%) had admission hypochloremia, and 1,242 (7.2%) died during hospitalization. Hypochloremia was associated with significantly higher in-hospital mortality (RR: 2.24, 95% CI: 1.60-3.13, Conclusion: Admission hypochloremia is associated with higher in-hospital mortality in patients with ADHF.
