Results of test–retest ICC Calculation for weeks 1–3 using mean-rating, absolute-agreement, and two-way mixed effects model and for weeks 1–2 using mean-rating, absolute-agreement, and two-way mixed effects model. CI, confidence interval; df, degrees of freedom; ICC, intraclass correlation coefficient; and ms, milliseconds.
