Table 2 Comparisons of canonical ρ coefficients between the KOOS and the two data sets
KOOS & X-ray grade (ρ and Pillai’s trace p-value) | KOOS & Biomechanical parameters (ρ and Pillai’s trace p-value) | Comparison using Fischer’s z (p and z values) | |
|---|---|---|---|
All subjects (N = 415) | ρ = 0.20 (p = 0.005) | ρ = 0.41 (p < 0.001) | p < 0.001* (z = -4.393) |
Women (N = 251) | ρ = 0.14 (p = 0.016) | ρ = 0.50 (p < 0.001) | p < 0.001* (z = -6.652) |
Men (N = 164) | ρ = 0.23 (p = 0.030) | ρ = 0.55 (p < 0.001) | p < 0.001* (z = -5.609) |
