Between-trial difference (90% confidence limits), typical error expressed as a coefficient of variation (CV, 90% confidence limits) and intraclass correlation coefficient (ICC, 90% confidence limits). The number of ‘#’ symbols stands for small, moderate, large and very large standardized difference and CV, respectively. For ICC values, the number of ‘*’ symbols refers to moderate, large and very large magnitudes, respectively.
