Pairwise multiple comparisons of the cycles N* obtained by the proposed method between the five variables investigated (hysteresis loop area h, elastic modulus E at high IOPs, residual strain εres, peak strain εpeak, and strain limit variation ΔεL) in the CCP and RCP protocols to characterize the preconditioning response. N* defines the number of cycles needed to reach preconditioned state. Paired t-tests were used for the statistical comparison.
