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

Dilated cardiomyopathy (DCM) is a complex disease characterized by cardiomyopathic hypokinesis and left ventricular interior hypertrophy. Cardiac rehabilitation (CR) is an established treatment for some cardiovascular diseases; however, the outcomes of early CR for patients with DCM remain underexplored. This study aimed to investigate the association between early CR and 90-day mortality in patients with DCM and symptomatic heart failure, using a national inpatient database in Japan from July 1, 2010, to March 31, 2020. We applied multiple imputation to the missing data and propensity score matching analysis. Early CR was defined as that initiated within 3 days of admission. The study included 30,296 eligible patients, including those with early CR (n = 3,130) and delayed or no CR (n = 27,166). The early CR group showed significantly lower 90-day mortality compared to the delayed or no CR group (odds ratio, 0.70, 95% confidence interval, 0.53-0.93; P = 0.01). Compared to the delayed or no CR group, the early CR group exhibited a higher activities of daily living score at discharge, but there was no significant difference in length of stay between the groups.
