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

TL;DR: Almost perfect agreement across different devices and moderate-to-high reliability across multiple time points, suggests the TEG6S platform can be used with haemostatic accuracy and generalisability, which has potentially significant implications for clinical practice and multi-site research programs.

Templating in uncemented total hip arthroplasty-on intra- and interobserver reliability and professional experience.
TL;DR: The reliability of digital templating of uncemented THA is good for acetabular and femoral components, but inferior for neck length, and precision does not rely on professional experience.
