Methods	Randomisation by opening sealed opaque envelope containing computer generated allocation code number. No attempt at masking given the manifest differences between medical and surgical interventions.
Participants	80 women with incomplete miscarriage or anembryonic pregnancy or missed miscarriage < 13 weeks, diagnosed by ultrasound. The data in this review are derived only from the subgroup with non‐viable pregnancies (n = 50) and not those with incomplete miscarriages. Women were reviewed 8‐10 hours after medical treatment; if they had empty uteruses on ultrasound examination they were discharged home; if not, surgical evacuation was arranged.
Interventions	Vaginal misoprostol 800 mcg once only (n = 26) versus surgical evacuation of the uterus (n = 24).
Outcomes	Need for surgical evacuation, symptoms including pain and bleeding, 'satisfaction'.
Notes	Authors contacted for information on outcomes according to indication for treatment. Only usable data currently available are on incidence of surgical evacuation.
Risk of bias
Bias	Authors' judgement	Support for judgement
Allocation concealment (selection bias)	Low risk	A ‐ Adequate
