ECV = External cephalic version; **Cell sizes less than 11 cannot be disclosed in accordance with data use agreement; Adjusted Odds Ratio (95 % CI); Adjusted for all characteristics in Table 1; All percentages weighted. The codes for endometritis are included in the definition for maternal sepsis. The odds presented are the odds of having the maternal outcome associated with successful external cephalic version compared with breech presentation delivery
