Vaginal misoprostol vs placebo

Opiate use (as a proxy measure for pain) for all participants on ITT (including those without confirmed AMI) · early fetal death (less than 24 weeks)

It is very uncertain whether vaginal misoprostol changes pain (opiate use) compared with placebo (very low certainty).

Misoprostol 800 µg plus mifepristone 200 mg vs mifepristone (200 mg) plus prostaglandin

Failure to achieve complete abortion · women undergoing first trimester abortion

Misoprostol 800 µg plus mifepristone 200 mg probably leads to lower failure to achieve complete abortion compared with misoprostol 400 µg plus mifepristone 200 mg (moderate certainty).
