Secondary analysis: Odds ratio (OR). Univariate analysis of potential prognostic factors. OR compared the proportion of Outcome Measures in Rheumatoid Arthritis Clinical Trials-Osteoarthritis Research Society International (OMERACT-OARSI) responders between 1 part of the population (event) and the rest of the population (nonevent). In this forest plot, each OR result was represented as a point with the 95% CI interval as a horizontal bar. At OR = 1 there was no probability for the event to be beneficial or unfavorable (P = 1). Each event (left column) was individually analyzed. The Kellgren-Lawrence (KL) radiologic osteoarthritis scale grade (I–IV) had the greatest influence, with KL grade II (relatively) favorable and KL grade IV (relatively) unfavorable.
