Comparison of screening tools based on 4 main principles of a screening tool according to ESPEN [9, 10].

Tools	Main principles according to ESPEN				Aim of each screening tool
	Current nutritional status	Weight loss	Reduced intake	Disease severity	Identify nutritional status	Identify need for nutritional intervention	Predict clinical outcome without intervention
PYMS	√	√	√	√*	√	√	√
STAMP	√		√	√	√	√
STRONG-kids	√ #	√	√	√		√	√

^#Current nutritional status by STRONG-kids is not evaluated by BMI but by subjective clinical assessments.

∗Disease severity in PYMS is not evaluated based on underlying disease that has nutritional implications as in STAMP or STRONG-kids, but on whether the child's nutrition will be affected by recent condition for at least the next week.
