-
aKappa statistic using binary outcome of clinical weakness for six-point scale (less than 48 out of 60); bkappa statistic using binary outcome of clinical weakness for four-point scale (less than 24 out of 36). n, number; ICC, interclass correlation coefficient; 95%CI, ninety-five percent confidence interval; ICU-AW, intensive care unit-acquired weakness; HGD, handgrip dynamometry.
