a. General linear model examining the relationship of OPRM1 allele A118G with overall pain intensity 6 weeks following MVC in women reporting high levels of pain prior to MVC
Independent variablea Beta SE P
In women with high pain prior to MVCb (n = 97)
 A118G allele −1.727 0.507 0.001

a

Study site was also included in model as a categorical variable

b

High pain prior to MVC was defined by a score of 10 or more (top quartile of individuals)
