FIGURE 2.

Smoking, CV events, and hypertension are associated with increased Artage_dif. Six binary variables were screened for potential effect on artAge_dif. The arterial age is increased significantly in patients who are smokers, have history of cardiovascular disease (CV event), or who are taking antihypertensive medicines (high BP). The corresponding p values (Kruskall–Wallis test): 0.016 (smoking), 0.029 (CV event), and 0.023 (high BP). Plots where the variable effects were significant are colored, while where the effect was not significant are in black (ACCP, anti-cyclic citrullinated peptides antibody; RF, rheumatoid factor).
