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

Effects of Posture and Anatomical Location on Inter-recti Distance Measured Using Ultrasound Imaging in Parous Women
TL;DR: The IRD can be measured reliably at all sites and postures and is wider at superior-umbilicus and umbilicus when upright compared with lying and there is a difference in IRD between all sites measured.

TL;DR: Although none of the resting energy expenditure calculated from predictive equations had very good agreement, Swinamer (1990) appears to provide relatively good agreement across three phases and could be used to predict restingEnergy expenditure when indirect calorimetry is not available.
