aWhere multiple individual antimuscarinic treatment episodes were joined to form a single period of current exposure, only the first matched episode during the period of current exposure was counted
bIncidence rates were calculated in terms of per 1000 person-years. CIs were calculated using Byar’s formula [23]
cHRs and corresponding CIs were calculated using CMA Version 3 software
dNon-naïve users had received a prescription for another OAB medication during the prior 12 months and naïve users had not received a prescription for another OAB medication during the prior 12 months
eThe number of AMI, stroke and CV mortality cases do not sum to the number of MACE cases. For patients with more than one of the individual outcomes, the earliest individual outcome was counted towards the MACE total
