Table 5 Cox regression models on DMARD retention rates

From: Methotrexate in rheumatoid arthritis is frequently effective, even if re-employed after a previous failure

Predictor Beta (SE) HR (95% CI) P
Re-employment (reference category: original course) -0.45 (0.21) 0.64 (0.42–0.97) 0.04
MTX dose (per each 2.5 mg/week dose increment) -0.03 (0.02) 0.97 (0.93–1.00) 0.06
Employment 1999 or later (reference category: 1998 or earlier) 0.49 (0.26) 1.63 (0.97–2.73) 0.06
  1. In total, 172 were evaluated patients. CI, confidence interval; DMARD, disease-modifying antirheumatic drug; HR, hazard ratio; MTX, methotrexate; SE, standard error.
