  1. Effects of MTX intake on laboratory parameters at last visit prior to the CV event/last follow up. ΔRDW Change in RDW between initial diagnosis and follow up prior to the CV event/last follow up in patients without CV event. Hb hemoglobin level. In the overall cohort RDW at established disease was not applicable as predictive marker for a CV event. A tendency with lower hemoglobin levels and higher CRP was shown. MTX intake significantly affected RDW
