Outcome Measures in Rheumatoid Arthritis Clinical Trials-Osteoarthritis Research Society International (OMERACT-OARSI) Response Criteria Initiative responders stratified with predictive factors. In these 2 scatter plots, each point represents a patient as a function of his age and body mass index (BMI). The distribution of the OMERACT-OARSI responders and nonresponders is random and does not indicate any of these predictive factors to be a determinant for the success or failure of the viscosupplementation with Arthrum 2.5% (LCA Pharmaceutical, Chartres, France). D = day; KL = Kellgren-Lawrence radiologic osteoarthritis scale.
