^aICC A was calculated by means of a two-factor model with mixed effects.

^bICC B was performed by means of one-factor model with random effects.

^cMDC was determined for each CI: $\sqrt{2}\times 1.96\times sw$ (95% CI); $\sqrt{2}\times 1.645\times sw$ (90% CI); $\surd \sqrt{2}\times 1.28\times sw$ (80% CI).
