“…reported. 1 We agree that caution should be exercised in interpreting ICC, which is distinct from the more commonly used Pearson or Spearman correlation coefficient. The latter is used to measure the monotonic relationship between two classes of measurements, in a linear or nonlinear fashion, respectively, without assuming that the two classes of measurements share their metric and variance.…”
