Nutrition-related indicators of patients screened for malnutrition risk by both the NRS-2002 and the PG-SGA and those screened for malnutrition risk by the NRS-2002 were analyzed, and there were no statistically significant differences between the two populations in terms of grip strength, albumin, and muscle index, as shown in Table 2. The gene discussed is ALB; the disease is malnutrition.
