  • The OR is given for every independent variable in the logistic regression with 95% CI for each PROM for function. All OR significant at the 0.05 level are shown. PASS: Patient Acceptable Symptom State; PROM: patient-reported outcome measure; NRS: numerical rating scale; WOMAC-PF: Western Ontario and McMaster Universities Osteoarthritis Index physical function subscale; LAI: Lequesne Algofunctional Index; LEFS: Lower Extremity Functional Scale; KOOS-PS: Knee Injury and Osteoarthritis Outcome Score, short version.
