Schorr 1997.

Methods	RCT.
Participants	Inclusion criteria: breech presentation or transverse lie. N = 69. Exclusion criteria: placenta praevia, fetal compromise, fetal growth restriction, ruptured membranes.
Interventions	Intervention:regional analgesia (C) + tocolytic. Epidural analgesia with 2% lidocaine with 1:200,000 epinephrine (N = 35); prehydration with 2000 mL lactated Ringer's solution vs no epidural (N = 34). All women received 0.25 mg terbutaline SQ. ECV attempted up to 3 times, with vaginal elevation of the presenting part when necessary. N = 35. Comparison:no regional analgesia + tocolytic. N = 34. 250 mg terbutaline given as adjunct.
Outcomes	Successful ECV, complications, mode of birth, presentation at delivery.
Notes
Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Low risk	Computer‐generated randomisation cards placed in permuted blocks of 10 by Division of Biostatistics.
Allocation concealment (selection bias)	Low risk	Allocation put in sealed opaque envelopes, and all investigators participating in clinical aspects of the study were blinded to the randomisation sequence.
Blinding of participants and personnel (performance bias) All outcomes	High risk	It is not possible to blind people to the use of epidurals.
Blinding of outcome assessment (detection bias) All outcomes	High risk	It is not possible to blind people to the use of epidurals.
Incomplete outcome data (attrition bias) All outcomes	Low risk	Although 5 women declined randomisation, there seemed to be no exclusions and no loss to follow‐up.
Selective reporting (reporting bias)	Unclear risk	We did not assess the trial protocol.
Other bias	Low risk	No differences in baseline data. No other biases apparent.
