Outcome reporting in randomized controlled trials (RCTs) on the pharmacological management of idiopathic overactive bladder (OAB) in women; a systematic review for the development of core outcome sets (COS).

Evidence on OAB management remains suboptimal and methodological limitations in randomized control trials (RCTs) affect their comparability. High quality meta-analyses are lacking. This study aimed to compare selection and reporting of outcomes and outcome measures across RCTs as well as evaluate methodological quality and outcome reporting quality as a first stage in the process of developing core outcome sets (COS).
