Model 1 simple multinomial logistic regression with PA none, some (>30 min brisk activity on 1–4 days) and meeting guidelines (>30 min brisk activity on 1–4 days) as the dependent variable. Model 2 adjusts for treatment, long-term condition, sex, age and IMD. All other treatment factors (been treated but still present/has not been treated/has come back/not certain).
