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

Tibial Plateau Fracture Characteristics: Reliability and Diagnostic Accuracy.
TL;DR: The recognition of tibial plateau fracture characteristics prove accurate and reliable on CT-based evaluation in this study and may be useful besides current classification systems, which do not account for all fracture components, in daily practice to help clinical decision making.

The interrater reliability of SAPS II and SAPS 3
TL;DR: Both SAPS II and SAPS 3 have adequate interrater reliability, but the standardized mortality ratios are still likely to be influenced by the rater's scoring practice.

TL;DR: The iPhone application appears to be a useful discriminative tool for the measurement of planar aCROM and associated coupling motions in patients with neck pain and fulfills the need for a valid, reliable, and feasible instrument in clinical practice and research.

Design and Interpretation of Studies of Differential Exposure Measurement Error
TL;DR: It is shown that two parameters need to be estimated in validity/reliability studies in order to interpret the results in terms of the bias in the odds ratio in an epidemiologic study that will use the measure.
