Note: PA = physical activity; MVPA = moderate-to-vigorous physical activity

Models include all predictors and are adjusted for main participants’ age, education, employment, household income, BMI, and WOMAC total score

Negative binomial regression

Logistic regression

Partner’s physical activity = physical activity outcome corresponding to the participant with osteoarthritis’ outcome in a given model
