R1 and R2 represent imaging at the same session. R3 was performed on a different day. CI is the 95% confidence interval. CR represents the coefficient of repeatability, expressed in parenthesis as the
This file shows that the sensor was able to provide repeatable results successfully during three repeatability tests at 30\% strain, 20\%, and 10\%, respectively.
Note—ICCs of less than 0.40 signifies poor agreement; 0.41–0.60, moderate agreement; 0.61–0.80, good agreement; and 0.81 or greater, excellent agreement. †ICC = intraclass correlation coefficients. ††
