NRS 2002	3 points	96	58	63	96
BMI	18.5 (kg/m^2)	100	35	4	100
FFMI
Female	15 (kg/m^2)	75	34	13	92
Male	17 (kg/m^2)	100	39	14	100
Female	16.2 (kg/m^2)	88	50	58	83
Male	19.4 (kg/m^2)	78	50	64	67
Protein	62 (g/l)	64	36	21	79
Albumin	32 (g/l)	100	38	7	100
Lymphocytes	1500 (10^9/l)	72	44	59	58
CRP	5 (mg/l)	55	26	35	44

SE—sensitivity, SP—specificity, PPV—positive predicted values, and NPV—negative predicted values.
