Exercise-Based Cardiac Rehabilitation for Patients After Heart Valve Surgery: A Systematic Review and Re-Evaluation With Evidence Mapping Study.
Synthesis in Clinical cardiology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
objectiveThis systematic review and evidence mapping study aims to assess the effects of exercise-based cardiac rehabilitation on clinical outcomes in patients after heart valve surgery. By consolidating and visualizing existing evidence, the study seeks to identify gaps in knowledge, evaluate the quality and breadth of current research, and provide guidance for clinical practice and future research. The evidence mapping will highlight under-researched areas and inform healthcare providers on effective strategies to enhance postoperative recovery.
methodsA comprehensive search was performed across multiple databases, including PubMed, Embase, Cochrane CENTRAL, Web of Science, CNKI, and Wanfang, up to May 2024. Two reviewers independently screened the articles, extracted relevant data, and assessed study quality. Study characteristics and outcomes were visualized using bubble plots.
resultsTen systematic reviews/meta-analyses met the inclusion criteria. Based on AMSTAR-2, two were rated "high quality," two "low quality," and six "very low quality." Using the GRADE system, of the 48 pieces of evidence across 10 outcomes, 1 was "high quality," 8 "moderate," 19 "low," and 20 "very low."
conclusionCurrent evidence indicates that exercise-based cardiac rehabilitation can enhance physical capacity, left ventricular ejection fraction, peak oxygen uptake, and daily living activities in heart valve surgery patients. However, more large-scale, high-quality studies are needed to verify its effects on all-cause mortality, quality of life, adverse events, return to work, and emotional health.
