Test–retest (week 1–week 2)
N 41
ICC 0.877
95% CI (0.770, 0.947)
Test–retest (sensitivity)
N 25
ICC 0.867
95% CI (0.583, 0.968)
  1. CI confidence interval, ICC intraclass correlation coefficient, N total sample size, NRS numeric rating scale
  2. *ICC and 95% CI were estimated through bootstrap (n = 1000)
  3. ICC was calculated using the ICC (2,1) model of Shrout and Fleiss (1979)
