Table 2 Nutritional screening results using two instruments and BMI in relation to three age groups

	Age group 1 65–74 years n = 1184	Age group 2 75–84 years n = 694	Age group 3 85+ years n = 228	P value
NUFFE-NO median (IQR)	3 (1–4) n = 1084	4 (2–6) n = 624	5 (3–8) n = 199	<0.001a
MNA-SF median (IQR)	14 (13–14) n = 1093	13 (12–14) n = 628	13 (11–14) n = 194	<0.001a
