^aPersistent duration defined as an encounter with the primary pain diagnosis at least once in each quarter for a 1-yr period; intermittent defined as more than one primary pain diagnosis over a 1-yr period, but not persistent.

^bChronic defined as more than one encounter with the primary pain diagnosis, at least 3 mo apart, over a 1-yr period.

^cCategories are not mutually exclusive.

^dT-tests with Levene’s test to determine equality of variances and Bonferroni’s correction to adjust for multiple comparisons were utilized to test for associations of persistent pain and chronic pain between types of pain categories. All pairwise tests were significant at p < 0.05, with the exception of other musculoskeletal-non-traumatic joint (p = ns) for persistent pain and peripheral/CNS-osteoarthritis for chronic pain (p = ns).
