Unadjusted mean SF-36 subscale scores in patient/visits in three groups: patients lacking a consistent change in NP events (top panel; Outcomes 0, 3 and 4; N=262); patients whose NP events all improve (middle panel; Outcome 1; N=295); patient whose NP events all worsen (bottom panel; Outcome 2; N=30). Dashed lines denote subscale scores from the first visit of the pair and solid lines denote the second set of scores. The SF-36 subscales are BP = Bodily pain, RP = Role physical, PF = Physical function, MH = Mental health, RE = Role emotion, SF = Social function, VT = Vitality, GH= General health.
