Pain intensity and opioid prescription by sex and the mediation effect of PCS

Note: This analysis involved using pain intensity and pain catastrophizing scores as predictors of opioid prescription. Pain catastrophizing scores were tested as a statistical mediator of the relationship between pain intensity and opioid prescription. Proportion column refers to proportion of direct effect of pain intensity on opioid prescription accounted for by PCS scores.
