	Criteria	n (%)
Normal (not malnourished)	At least one phenotypic criteria: •<5% weight loss past 6 mo •Normal weight •FFMI between >10th and <90th percentile •FMI between >10th and <90th percentile •HGS between >10th and <90th percentile At least one etiologic criteria: •Normal nutritional intake for >1 wk •Chronic inflammation Combination of both a phenotypic and etiologic criteria	47 (98) 27 (56) 39 (81) 37 (77) 44 (92) 46 (96) 42 (88) 37 (76)
Moderately malnourished	At least one phenotypic criteria: •>5% weight loss past 6 mo •Underweight •FFMI 5th to10th percentile •FMI 5th to10th percentile •HGS 5th to10th percentile At least one etiologic criteria: •Reduced nutritional intake for >1 wk •Chronic inflammation Combination of both a phenotypic and etiologic criteria	1 (2) 2 (4) 9 (19) 0 (0) 2 (4) 2 (4) 6 (12) 0 (0)
Severely malnourished	At least one phenotypic criteria: •>10% weight loss past 6 mo •Severe underweight •FFMI <5th percentile •FMI <5th percentile •HGS <5th percentile At least one etiologic criteria: - Reduced nutritional intake for >1 wk - Chronic inflammation Combination of both a phenotypic and etiologic criteria	0 (0) 0 (0) 0 (0) 0 (0) 0 (0) 2 (4) 6 (12) 0 (0)
Obese	High BMI and high FMI	11 (23)
Obese sarcopenia	High BMI and high FMI and low HGS	0 (0)
Sarcopenia	Low FFMI and low HGS	0 (0)

BMI, body mass index; FFMI, fat-free mas index; FMI, fat mass index; HGS, handgrip strength; ICU, intensive care unit

Severe underweight defined as BMI <18.5 kg/m² if <70 y or <20 kg/m² if ≥70 y, underweight as BMI <20 kg/m² if <70 y or <22 kg/m² if ≥70 y, and obese as BMI >30 kg/m²[44].

High FMI defined as P>90th percentile and both low FFMI [34] and low HGS defined as P<10th percentile [36].

Reduced nutritional intake defined as <50% of energy requirement for >1 wk [44].
