After 2 years, the patients were classified as receiving disease\u2010modifying antirheumatic drugs (DMARDs), having synovitis, having joint erosions typical of RA, having a rheumatologist diagnosis of RA with &gt;50.0% certainty, having a no better alternative diagnosis with &gt;50.0% certainty, and having a diagnosis of RA using the 1987 ACR criteria and the 2010 ACR\/EULAR criteria. Agreement among these criteria was assessed based on Cohen's kappa coefficient, where \u22650.80 = excellent, 0.60\u20130.79 = good, 0.40\u20130.59 = moderate, and &lt;0.40 = poor.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Of the 692 evaluated patients, 544 (78.6%) had persistent arthritis (defined as synovitis, ongoing DMARD treatment, or both) after 2 years.

Agreement among all criteria was poor (estimated \u03ba = 0.09\u20130.43), except when including a rheumatologist diagnosis of RA with &gt;50.0% certainty or a no better alternative diagnosis with &gt;50.0% certainty (estimated \u03ba = 0.69\u20130.81). The strongest associations with a rheumatologist diagnosis of RA with &gt;50.0% certainty were the 2010 ACR\/EULAR criteria and the combination of no better alternative diagnosis, persistent
