The proportion of aortic adventitia biopsy specimens in which CD68+ macrophages were detectable (63% of RA specimens and 56% of non‐RA specimens) and the number of CD68+ cells per section (Figure 1A) were similar in CVD patients with RA and those without RA (additional information is available upon request from the corresponding author). The gene discussed is CD68; the disease is rheumatoid arthritis.
