Table 3: Z-score data shown as means with 95% confidence interval within brackets in individuals with osteoarthritis (OA).
Statistically significant differences are highlighted in bold. The p-value in the column all OA is referred to when we
compared all groups with OA irrespectively of affected joint and the p-value in the column lower extremity when we
compared the groups with OA only in the lower extremity.
