Cumulative retention rates of methotrexate therapies

<b>Copyright information:</b>Taken from "Methotrexate in rheumatoid arthritis is frequently effective, even if re-employed after a previous failure"Arthritis Research &amp; Therapy 2006;8(2):R46-R46.Published online 24 Feb 2006PMCID:PMC1526609. Kaplan-Meier analysis of retention rates of methotrexate. The different panels show the overall drug retention, retention of drug effectiveness, and retention of drug safety for original therapy (grey lines; oMTX) and re-employed therapy (black lines; rMTX). Overall retention rates were similar between the two groups (panel a: = 0.31, by log-rank test). Likewise, retention because of safety was similar between groups (panel c: = 0.23). Retention because of effectiveness was better for the rMTX group (panel b: &lt; 0.01).
