  1. Demographics and laboratory parameters at initial diagnosis of RA according to a CV event during follow up, p values for statistical significances between the two groups are given by Mann Whitney U test, respectively cross tables, significance level at p level ≤ 0,05, SD standard deviation, n sample size, RF rheumatoid factor, ACPA anti citrullinated peptide antibodies, RDW red cell distribution width
