As shown in Figure 3, the odds of having aMCI or AD in individuals with high NLR were still significant for aMCI (OR: 2.58, 95%CI: 1.36–4.89) and AD (OR: 3.13, 95%CI: 1.47–6.70), after multivariate adjustment for potential confounders, including age, sex, smoking, comorbidities, albumin (NLR vs. albumin: r = −0.100, p=0.04), and triglycerides (NLR vs. triglycerides: r = −0.126, p=0.01). Here, ALB is linked to Alzheimer disease.
