Table 2 The MID estimates from the ROC analysis

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 MID Sensitivity Specificity AUC (95 % CI)
NRS pain 2.5 0.79 0.82 0.84 (0.75 to 0.93)
PRWHE total score 10 0.91 0.86 0.93 (0.89 to 0.97)
PRWHE pain subscale 7.5 0.87 0.91 0.93 (0.89 to 0.96)
PRWHE function subscale 6.0 0.86 0.82 0.90 (0.85 to 0.96)
  1. NRS pain from 0 to 10 (0 = no pain), PRWHE total score from 0 to 100, PRWHE pain and function subscales from 0 to 50 (0 = optimal situation)
