Multivariate logistic regression analysis was performed on the factors of significant statistical differences in the above from univariate analysis, and the findings presented that age (OR = 12.336, 95% CI: 4.203-36.208; P < 0.001), hs-CRP (OR = 3.346, 95% CI: 1.833-6.122; P < 0.001), HB (OR = 0.984, 95% CI: 0.973-0.995; P = 0.005), ALB (OR = 0.892, 95% CI: 0.808-0.989; P = 0.024), BMI (OR = 0.803, 95% CI: 0.734-0.879; P < 0.001) and BWL (OR = 5.981, 95% CI: 2.700-13.056; P < 0.001) were independent risk factors for malnutrition in GC (Figure 2). This evidence concerns the gene CRP and nutritional deficiency disease.
