Values reported are transformed scores with ranges from 0 to 100, where higher scores represent better function.
Values are reported in outcome measure original scale where higher scores represent better function for the ADLS and LEFS, and lower scores represent better function for the WOMAC.
correlation significant at the 0.01 level
SEM=Sx*√(1−rxx), where Sx=standard deviation at baseline of the measurement tool from the total sample and rxx=reliability coefficient for that measurement tool
MDC 95%=SEMx*1.96*√(2),
MDC 90%=SEMx*1.64*√(2)
Rho=Spearman’s correlation coefficient between each outcome measure and the GRC
AUC= probability that the outcome measure would be able to distinguish an individual who perceives them self to be improved from an individual who does not
GRI= mean change of those improved/standard deviation of change of those not improved
