Objective: This research aimed to make statements regarding the reduction in atrial fibrillation (AF) risk due to acupuncturE Design and method: The Kaplan-Meier method was performed to calculate cumulative incidence of outcomes for each group, and the log-rank test were performed to compare differences between groups. Results: In CHA2DS2-VASc scores of 0~1, 2~3, 4~5, and > 5, cases with acupuncture were all associated with decreased incidence of atrial fibrillation (aHR, 0.46 with 95% CI, 0.42–0.51; p-value, < 0.001 in the CHA2DS2-VASc scores of 0~1; aHR, 0.53 with 95% CI, 0.50–0.57; p-value, < 0.001 in the CHA2DS2-VASc scores of 2~3; aHR, 0.56 with 95% CI, 0.52–0.61; p-value, < 0.001 in the CHA2DS2-VASc scores of 4~5; and aHR, 0.64 with 95% CI, 0.55–0.74; p-value, < 0.001 in the CHA2DS2-VASc scores of > 5). Conclusions: Protective effect of acupuncture on AF in a relatively dose dependent manner was observed in this study.
