Spearman correlation coefficients between change in scores from 10 PROMIS CAT instruments, SF36

subscales, SF-36 summary scores and physician- and patient global assessment scores.

PROMIS = Patient-Reported Outcomes Measurement Information System, CAT = Computer adaptive testing, SF36 = Short form 36, Vital. = Vitality, PF = Physical function, BP = bodily pain, SF = social function, MH = mental health, GH = general health, RE = role emotional, RP = role physical, PCS = physical component summary MCS = mental component summary, PtGA = Patient global assessment for disease activity, PhGA = Physician global assessment for disease activity.
