  • N= number of patients with both a flare and non-flare entry for each variable; CI=confidence interval

  • Higher variable scores indicate more positive outcomes (e.g. a higher pain score indicates less pain)

  • ^Estimated difference between flare and non-flare entries (e.g. on average, the mean pain score of a flare entry is 0.67 [0.56– 0.78 CI] less than a non-flare entry)
