Abstract

Objective: To define sample size requirements for establishing clinical serial monitoring protocols.

Design: The 95% confidence bound of a critical difference score is defined and used to identify false-negative regions suitable for sample size calculation.

Results: Reference subject sample sizes vary from about 40 to 480 subjects, depending on the minimum acceptable error rates of the clinical protocol.

Conclusions: Sample size requirements for establishing test-retest standards are generally defined and suitable for any serial monitoring protocol.
