ALB and Zinc deficiency: Results of multivariable regression analysis showed that non–daily alcohol consumption (OR [odds ratio] = 1.39, 95% CI [confidence interval] = 1.05‐1.84, P = .02), Hb (OR = 1.16, 95% CI = 1.02‐1.31, P = .03), Alb (OR = 12.49, 95% CI = 6.69‐23.32, P < .01), and eGFR (OR = 1.01, 95% CI = 1.00‐1.02, P = .04) were significantly associated with serum zinc deficiency/marginal deficiency in men.
