Correlation coefficient*p Value
*Spearman’s correlation coefficient; †WOMAC pain, stiffness, and function subscales (higher score indicates worse symptoms); ‡results of SF-36 standardised to Australian normal values (lower score indicates worse function).
Increased pain score†0.130.14
Increased stiffness score†0.090.32
Increased function score†0.150.10
Decreased physical function score‡−0.070.42
Decreased mental function score‡0.180.05
