TABLE 2.

Patient characteristics, continuous variables. The arteries are approximately 10 years older in RA than in the matched control group. Disdur: disease duration, CCS: coronary calcium score, CRP: C-reactive protein, artAge: calculated arterial age using Eq. 1, artAge_dif: arterial age difference from the median of the race-, sex-, and age-matched control population.
