BPI: Bootstrapped percentile interval; OA: osteoarthritis.

ⁿ⁺Number of missing values; ^ato few cases per outcome for performing logistic regression, ^badjusted for age, sex, number of knee related contacts, knee related quality of life, and presence of a total knee replacement.

*Statistically significance p < 0.05.
