Although the malnutrition rates varied according to different malnutrition assessment criteria, the OCC subgroup exhibited no statistically significant difference from the NOCC subgroup in the different criteria: PG-SGA-defined malnourished status (81.2% for OCC vs. 90.7% for NOCC, p = 0.328), BMI < 18.5 kg/m2 (20.3% for OCC vs. 20.4% for NOCC, p = 0.991), albumin < 3.5 g/dL (18.8% for OCC vs. 20.4% for NOCC p = 0.832), TLC < 1.5 × 103 cells/mm3 (46.4% for OCC vs. 33.3% for NOCC, p = 0.144). The gene discussed is ALB; the disease is nutritional deficiency disease.
