CONCLUSIONS	The RCT design , combined with access to clinical records at all provincial abortion clinics , and to information in provincial single-payer linked administrative health databases , birth registry , and hospital records , offers a unique opportunity to determine if a novel IUD has a comparable expulsion rate to that of the current standard IUD in Canada , in addition to the first opportunity to determine pregnancy rate and method satisfaction at 1 year post-abortion for women choosing a range of post-abortion contraceptive options .\
