As shown in Table 4, with each 1-SD increase in apo B/apo A1 ratio level in patients with diabetes, the adjusted HRs for CV and all-cause mortality were 1.61 (95% CI, 1.27–2.05; P < 0.001) and 1.49 (95% CI, 1.25–1.78; P < 0.001), respectively, the adjusted SHRs for atherosclerotic and non-atherosclerotic CV mortality were 1.96 (95% CI, 1.43–2.68; P < 0.001) and 0.79 (95% CI, 0.57–1.12; P = 0.184), respectively. This evidence concerns the gene APOB and diabetes mellitus.
