This systematic review and <i>meta</i>-analysis aimed to determine the prevalence and incidence of AF in the IBD population.<h4>Methods</h4>We conducted a systematic search of the PubMed and Embase databases for relevant studies published up to February 2024. We used the random-effects model to pool the prevalence and incidence rates of AF among IBD patients. The subgroup analyses were performed according to the IBD type.<h4>Results</h4>A total of twenty-five studies were included. The pooled prevalence of AF among IBD patients was 6.23 % (95 % confidence interval [CI]: 4.99 %-7.47 %). The incidence rate of AF among IBD patients was 3.53 % (95 International journal of cardiology.
