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
backgroundCardiorespiratory fitness (CRF) is a powerful predictor of cardiovascular morbidity and mortality. The cardiopulmonary exercise test (CPET) is considered a gold standard in assessing CRF. Patients with myocarditis are recommended to abstain from exercise because of the risk of sudden cardiac death (SCD). Therefore, the clinical benefit of exercise-based cardiac rehabilitation (CR) has not been previously established in this population.
objectiveThe aim of this study is to assess the CRF of myocarditis and the safety and effectiveness of an exercise-based CR program in these populations.
methodA total of 70 consecutive patients with a diagnosis of myocarditis admitted to Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology between October 2021 and December 2024 were enrolled in the current study. CPET was performed within 3-6 months of hospital discharge. The exercise-based CR program was performed for 3 months. The protocol included biomarker analysis, CPET, and standard-of-care echocardiography (including resting left ventricular ejection fraction and global longitudinal strain [GLS]). Data were collected at admission and 3 months after discharge.
resultsA total of 70 patients with myocarditis were enrolled. Among them, 47 patients completed the rehabilitation program and had complete follow-up assessments, including cardiopulmonary exercise testing, and were included in the final analysis. In comparison with NFM, patients with FM were more often female, and had higher levels of creatine kinase (CK), lactate dehydrogenase (LDH), urea nitrogen (UN), N-terminus probrain natriuretic peptide (NT-proBNP), fasting blood glucose (FBG), and white blood cell (WBC). For FM, echocardiography revealed more frequently signs of left ventricular (LV) dysfunction in the form of a reduced ejection fraction (p < 0.01), and lower GLS (p < 0.01) in contrast to NFM. CPET results showed that FM patients had markedly lower exercise capacity, impaired ventilatory efficiency, and pulmonary function (p < 0.05). After the 3-month exercise-based CR program, both groups demonstrated significant improvements in peak VO
conclusionCRF was substantially impaired in patients recovering from myocarditis, particularly among those with fulminant presentations. Participation in a structured 3-month exercise-based CR program was feasible and was associated with favorable changes in exercise capacity and cardiopulmonary performance.
