Version: 0Date: 12 Aug 2019
Reviewer: Kedra Wallace
Reviewer's report:
- What percentage of these unintended pregnancies are due to force/rape?
- What are low-efficacy contraceptive methods and what are high-effective methods? What is aTier 1 or Tier 2 method of contraception?- Please discuss how requiring women to be sexually active on a monthly basis could be a studylimitation. Could it be that some women became pregnant after not being sexually active for awhile and had a single sexual encounter? Under the current criteria they would not qualify for thisstudy.- If the women enrolled in the study were 18-45yrs of age, what category did the 18-20 fall into forpotential correlations of pregnancy likelihood underestimation? If there were not any womenunder the age of 21 in this study please adjust the methodology.
