<div>Effects of EA on pH, BE, admission to NICU, APGAR scores and perinatal
mortality were tested with linear or logistic regression, respectively,
as</div><div>appropriate. Propensity scores were used as covariates to adjust for
potential risk factors (A). Duration and mode of delivery and episiotomy
were</div><div>included in all models as further confounders (B). Due to missing values
in the outcome variables, the absolute number of cases for the
underlying</div><div>models differed between endpoints. In the logistic regressions, a
positive effect estimate is understood as a higher chance of the
endpoint to</div><div>happen, when EA is applied. In linear regressions, the effect estimates
are the proposed mean changes in the end-point variable with EA being
