Results: the Pain Composite Score, total (PCS_total), was used as the dependent variable in multivariable, multi-level regression models in (A) results for the total cohort and (B) for women with regional anesthesia. Standardized regression coefficients (β_z) including 95% confidence intervals (95% CI) and p-values (p), are shown. Significant p-values are printed in bold.
