Atrial fibrillation recurrence after rhythm control: gaps in outpatient risk factor management in a single-centre retrospective cohort study.

Although increasing uncontrolled risk factor burden was associated with a numerical trend toward higher AF recurrence, this did not reach statistical significance; this may reflect limited power, and the finding should be interpreted as hypothesis-generating rather than evidence of no clinically relevant gradient.
