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.
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
backgroundConstipation is frequently observed in patients with chronic heart failure and has been linked to a heightened risk of adverse heart failure outcomes. Although laxatives are commonly prescribed, the optimal choice for individuals with heart failure remains uncertain. We evaluated the association between magnesium oxide use and heart failure prognosis in patients with chronic heart failure.
methodsA retrospective observational study was conducted on patients admitted to our hospital for heart failure between January 2020 and December 2023 who were continued to be prescribed the same laxatives after discharge. Patients who received magnesium oxide for regular use were categorized into the magnesium oxide group, while all other patients comprised the nonmagnesium oxide group. The primary endpoints were heart failure-related readmission and all-cause mortality, while the secondary endpoint was a composite of both. Propensity scores were calculated based on baseline patient characteristics and used to perform 1:1 nearest-neighbor matching.
resultsDuring the study period, 171 outpatients with heart failure were prescribed laxatives after hospital discharge, with 74 patients included in the magnesium oxide group. Using propensity score matching, a cohort of 41 matched pairs was established. After matching, the analysis showed that the hazard ratio (HR) for first readmission within 360 d was 0.33 (95% confidence interval [CI]: 0.10-0.92, p = 0.035). Additionally, the combined risk of first readmission and all-cause mortality was associated with an HR of 0.30 (95% CI: 0.11-0.82, p = 0.019).
conclusionMagnesium oxide was strongly associated with a lower risk of readmission and/or death in patients with heart failure who were prescribed laxatives.
