Methods	Quote: "Random allocation". No details. Zeynep Kamil Women and Childrens Hospital, Istanbul, Turkey. No information on study duration.
Participants	65 women in Istanbul, Turkey, with ultrasound‐diagnosed fetal death in second trimester.
Interventions	Vaginal misoprostol 200 mcg (n = 32) vs intracervical dinoprostone 0.5 mg (n = 33). Intravenous oxytocin started after 6 hours if no 'effective contractions'.
Outcomes	Complete miscarriage. Adverse effects.
Funding	No information on funding.
Declarations of interest	No information on conflicts of interest.
Notes	Misoprostol dose reported as 200 mg. Assumed to be 200 mcg. Time to miscarriage not included as standard deviations seem incorrect.
Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Unclear risk	Comment: quote: "Random allocation". No details.
Allocation concealment (selection bias)	Unclear risk	Comment: no information on allocation concealment.
Incomplete outcome data (attrition bias) All outcomes	Low risk	Comment: 65 patients were randomised, for all of them outcomes were presented, there seems to be no missing data.
Selective reporting (reporting bias)	Low risk	Comment: misoprostol dose reported as 200 mg. Assumed to be 200 mcg. Other than these findings no signs of selective or unclear reporting.
Other bias	Low risk	No other source of bias could be detected
Blinding of participants and personnel (performance bias) All outcomes	High risk	Comment: no information on blinding of participants and personnel, considering the type of intervention (different number and shape of tablets used) probably not done.
Blinding of outcome assessment (detection bias) All outcomes	High risk	Comment: no information on blinding of outcome assessment, probably not done.
