Sample size and optimal designs for reliability studies
TLDR
A functional approximation to earlier exact results is shown to have excellent agreement with the exact results and one can use it easily without intensive numerical computation.Abstract:
A method is developed to calculate the required number of subjects k in a reliability study, where reliability is measured using the intraclass correlation rho. The method is based on a functional approximation to earlier exact results. The approximation is shown to have excellent agreement with the exact results and one can use it easily without intensive numerical computation. Optimal design configurations are also discussed; for reliability values of about 40 per cent or higher, use of two or three observations per subject will minimize the total number of observations required.read more

Reliability and normal values of various computed tomography methods for quantifying distal radioulnar joint translation.
Min Jong Park,Jong Pil Kim +1 more
TL;DR: This study suggests that the subluxation ratio method is the most useful technique for measuring translation of the distal radioulnar joint as a result of its reliability and simplicity.
