 Relation between patient and physician characteristics and non-adherence to EULAR 2000 non-pharmacological recommendation*

VariableOdds ratio (95% CI)†n (%)
*“Optimal management of knee osteoarthritis requires a combination of pharmacological and non-pharmacological treatment modalities. Non-pharmacological treatment of knee osteoarthritis should include regular education, exercise, appliances (sticks, insoles), and weight reduction.”
†Multilevel regression logistic model representing probabilities of non-adherence as odds ratios with 95% confidence intervals (n = 2111). An odds ratio >1 means a higher probability of non-adherence to the recommendation.
