The mean baseline DAS28 was 1.96\u00a0\u00b1\u00a00.56. The median cumulative MTX dose was 11.7\u00a0g; the median duration of exposure to MTX was 19\u00a0years. Following MTX discontinuation, flare occurred in 43 (44.3%) patients; the median time to flare was 99 (28\u2010168) days. According to univariate logistic regression analysis, C\u2010reactive protein, erythrocyte sedimentation rate (ESR) at discontinuation, the average ESR in the 6\u00a0months before discontinuation of MTX, a weekly dose of MTX before discontinuation, and use of other conventional synthetic disease\u2010modifying antirheumatic drugs were associated with a higher risk of disease flare.
