  1. The Intraclass correlation coefficient (ICC), the standard error of measurement (SEM), the smallest detectable difference (SDD) and the % of the grand mean for the intra- and inter-observer highest MVPT value of knee extension strength measurements in patients with haematological malignancies are presented.
