Significant differences in lethality between diabetic sepsis patients and non-diabetic patients (Chi-square 7.698 (Yates); OR = 2.76, 95% CI: 1.389 – 5.484, p = 0.006) were due to significantly increased lethality in diabetes patients with AT or TT AGTR1 genotype: OR = 11.034, p = 0.007 by Fisher test (Fig. 1). This evidence concerns the gene AGTR1 and diabetes mellitus.
