Nutritional status and test-retest reliability

MNA-SF results	Total sample (n = 122)	TAVI (n = 58)	AVI (n = 21)	PCI (n = 43)	P-value
Results are presented as mean ± SD or n (%). CI: confidence interval; ICC: intraclass correlation coefficient with < 0.5 "poor", 0.5-0.75 "moderate", 0.75-0.9 "good", > 0.9 "excellent"; MDC: minimal detectable change; MNA-SF: Mini Nutritional Assessment-Short Form with < 12 points "(risk of) malnutrition".
