  1. CI 95%: 95% confidence interval of the proportion.
  2. * Other: includes the other options in the questionnaire: "there is no exact time", "I am not sure", "I do not have an opinion," and "sometime before fertilization".
  3. Embryonic loss' cause: refers to whether it is important to distinguish natural embryo losses from those that may be caused by birth control methods.
