Correlations between process of care variables and interventions Women in midwife-led care at onset of labour Intrapartum referral to obstetricianled care Planned home birth Actual home birth Episiotomy in midwife-led care at time of birth Episiotomy in all births Oxytocin postpartum Women in midwife-led care at time of birth rho = 0.84 rho = - 0.66 rho = 0.73 rho = 0.73 rho = - 0.06 rho = - 0.20 rho = - 0.57 Intrapartum referral to obstetrician-led care rho = - 0.40 rho = - 0.15 rho = - 0.21 rho = - 0.33 rho = - 0.26 rho = 0.28 Planned home rho = 0.69 rho = 0.98 rho = - 0.48 rho = - 0.57 rho = - 0.75 Actual home birth rho = 0.69 rho = - 0.53 rho = - 0.60 rho = - 0.79 Episiotomy in midwife-led care at time of birth rho = - 0.31 rho = 0.37 Episiotomy in obstetrician-led care at time of birth rho = - 0.31 rho = 0.96 Artificial rupture of membranes rho = - 0.21 rho = - 0.27 rho = - 0.24 rho = - 0.27 rho = 0.28 rho = 0.29 All correlations are based on adjusted ORs of the intervention rates (adjusted for parity, maternal age, ethnic background, socioeconomic position and urbanisation). A p-value of 0.05 corresponds with a correlation of rho ≥ 0.57 or ≤ - 0.57 (95% confidence intervals 0.001-0.86). Since the sample size for all measured correlations is the same, namely 12 regions, the correlation is significant at the same value of rho for all measured correlations. Correlations with rho ≥ 0.60 or ≤ - 0.60 are indicated in bold type since they are considered strong.
