The univariate analysis indicated that patients with MAKEs at 30 days were older (unadjusted odds ratio (ORs) = 1.07, 95% CI =1.02–1.12, p = 0.003), had a history of type 2 diabetes (ORs = 6.19, 95% CI 0.70–54.15, p = 0.099), had higher urinary IL-6 (ORs = 2.13, 95% CI = 0.95–4.75, p = 0.064), had higher urinary N-Gal (ORs = 1.01, 95% CI = 0.99–1.04, p = 0.089), and had higher ΔP (ORs = 1.36, 95% CI = 1.06–1.74, p = 0.013). Here, IL6 is linked to type 2 diabetes mellitus.
