Table 3 The MID estimates from the mean difference of change (MDC), mean change (MC), ROC and Predictive modelling method

From: Minimal important difference and patient acceptable symptom state for the Numerical Rating Scale (NRS) for pain and the Patient-Rated Wrist/Hand Evaluation (PRWHE) for patients with osteoarthritis at the base of thumb

Outcome measure MDC MC ROC Predictive
NRS pain 2.0 (0.8 to 3.2) 2.8 (2.1 to 3.5) 2.5 (2 to 2.9) 2.5 (2.0 to 2.9)
PRWHE total score 22 (16 to 28) 24 (20 to 28) 10 (8 to 23) 20 (14 to 24)
PRWHE pain subscale 12 (8 to 15) 13 (10 to 16) 7.5 (3 to 8) 10 (7 to 12)
PRWHE function subscale 10 (6 to 14) 11 (9 to 13) 6.0 (4 to 16) 10 (7 to 13)
