(a–b) Effect of cyclic creep on median secant modulus. Between cycles 1 and 20, (a) Esecant50% in healthy specimens decreased significantly while (b) in IAT specimens, there was a trend suggesting the possibility of such an effect (p=0.056). (c–d) Effect of cyclic creep on median secant modulus. For both (a) healthy and (b) IAT donors, Esecant50% was lower for slow loading (−5%/second) than for fast loading (−0.5%/second).
