Prognostic effects of cardiac rehabilitation in heart failure patients classified according to physical frailty: A propensity score-matched analysis of a nationwide prospective cohort study.

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
Background: Research regarding cardiac rehabilitation (CR) in the prognosis of heart failure (HF) patients and frailty remains lacking. Here, the effects of CR on the 2-year prognosis of HF patients were examined according to their frailty status. Methods: This multicenter prospective cohort study enrolled patients hospitalized for HF. Patients who underwent ≥1 session per 2 weeks of CR within 3 months after discharge were categorized in the CR group. Patients were divided in a non-frailty (≤8 points) and physical frailty group (≥9 points) based on their FLAGSHIP frailty score. The score is based on HF prognosis, with a higher score indicating worsened physical frailty. A propensity score-matched analysis was performed to compare survival rates between the two groups according to their physical frailty status. Endpoints included HF re-hospitalization and all-cause mortality during a 2-year follow-up period. Results: Of 2697 patients included in the analysis, 285 and 95 matched pairs were distributed in the non-frailty and physical frailty groups, respectively, after propensity-score matching. CR was associated with lower incidence of HF rehospitalization in both non-frailty (hazard ratio 0.65; 95% confidence interval 0.44-0.96; p = 0.032) and physical frailty (0.54; 0.32-0.90; p = 0.019) groups. CR was not associated with all-cause mortality in either group (log-rank test, p > 0.05). Conclusion: These findings suggest the effects of CR on reduced HF rehospitalization, regardless of physical frailty status.
