Compared to participants without SeD, participants with SeD were more likely to smoke (368 (32.1%) vs. 1133 (26.6%), p < 0.001), more likely to have a history of myocardial infarction (92 (8.1%) vs. 241 (5.7%), p = 0.006), more likely to have anemia (144 (12.5%) vs. 370 (8.7%), p < 0.001) or ID (207 (17.9%) vs. 590 (13.7%), p < 0.001), and had higher levels of C-reactive protein (CRP) (1.5 (0.7, 3.4) mg/L vs. 1.3 (0.6, 2.8), p < 0.001) (Table 1). The gene discussed is CRP; the disease is anemia (phenotype).
