From the article:

At 12 months, the AF recurrence rate was significantly lower in the exercise group (60%) compared to the control group (80%), with a hazard ratio of 0.50 (95% confidence interval 0.33-0.78; p=0.002). Dr. Elliott said: “Put simply, this means a larger number of patients in the exercise group could maintain a normal heart rhythm without needing invasive interventions or continued use of drugs.”

Patients in the exercise group also had a significant reduction in the severity of their symptoms at 12 months compared to the control group. “This means that patients reported less severe palpitations, shortness of breath and fatigue,” said Dr. Elliott.
