Female or male.
Of 301 patients who discontinued their baseline method at six months, 258 (85.7 percent) wanted to prevent pregnancy at time of survey. Of 646 patients who discontinued their baseline method at 24 months, 503 (77.9 percent) wanted to prevent pregnancy at time of survey. Of 806 patients who discontinued their baseline method at 36 months, 592 (73.5 percent) wanted to prevent pregnancy at time of survey.
Unable to report current use of other contraceptive methods (i.e., condoms, other barrier methods, withdrawal, fertility awareness-based methods) because of survey limitations.
Defined as the contraceptive method received at or within 30 days of the initial Z-CAN visit.
Patients who received implant re-insertion after implant expiration were not considered as patients who discontinued their baseline Z-CAN contraceptive method.
