*Correct use of mifepristone and misoprostol is defined as interval between mifepristone and misoprostol administration between 24 and 72 hours.
†Participants reporting they were certain that they had passed pregnancy tissue following misoprostol administration. ‘No’ means that they did not pass pregnancy, ‘Not sure’ means they do not know if they passed the pregnancy or not, ‘Unknown’ indicates the number of people not responding to the question.
‡ Misoprostol administration (induction) until expulsion of pregnancy intervals in hours, when participant was certain pregnancy expelled.
