Table 1 P-values, showing significant differences within all pairs of study groups, formed between Group 1 (USS), Group 2 (POLY) and Group 3 (MONO), with regard to the initial and secondary torsional stiffness (the latter after 20,000 cycles)
Group pairs | Torsional stiffness, Nm/deg | |
|---|---|---|
Initial | Secondary | |
USS-MONO | 0.002 | 0.002 |
USS-POLY | 0.001 | 0.001 |
MONO-POLY | 0.015 | 0.047 |
