Numbers indicate percentage of women in each group who were taking various classes of medication for pain relief prior to enrollment. Note that, percentages do not always sum to 100 % within each group because some women reported taking more than one pain medication. Chi-square analyses revealed no difference in the distribution of medication usage between NFR-R and NFR-NR groups (p >0.05)
