- For each of the six CoP-based variables, reliability data were reported in eyes open (EO) and eyes closed (EC) conditions. For all the CoP-based variables, ICC2,k with its 95% confidence interval (95% CI) and SRD expressed in percentage of the mean measurement between session 1 and 2 (SRD

, in the last column, not to use for clinical practice but to compare the magnitude of the measurement error between the different CoP-based variables) were reported. For CoP-based variables without heteroscedastic distribution of random error distribution, standard deviation of random error (SD), standard error of measurement (SEM) and small real difference (SRD) expressed in the original units of measurement (o.u.) were reported. For CEAREA, with heteroscedastic distribution of random error distribution, standard deviation of random error expressed in percentage of the individual means (SDP), SEM and SRD expressed in percentage (SEMP and SRDP in%) or as a ratio (SEMR and SRDR, obtained after natural logarithmic transformation) were reported.
