Impact of repeated measures of joint space width on the sample size calculation: An application to hip osteoarthritis

Abstract

The aims of the study were to investigate the impact of aggregation of repeated readings (a) on minimising variability of joint space width (JSW) measurements based on calculation of the smallest detectable difference (SDD) and (b) on sample size calculation in a hip OA randomized controlled trial (RCT).
