The third important finding of this study is that increased albuminuria was significantly correlated with most of the measured malnutrition-related indices (low body weight, BMI and abdominal circumference, low serum albumin, vitamin D, total and HDL-cholesterol, low adipose tissue and low visceral fat on BIA, and low MNA and GNRI scores), increased age, and lower renal function (high urea and creatinine and low eGFR) in the enrolled patients. The gene discussed is ALB; the disease is nutritional deficiency disease.
