SF cut-off	n	Sensitivity	Specificity	Positive LR	Negative LR	DOR
One value < 10th percentile
Calvert et al. [25]	381	0.60 (0.39-0.79)	0.76 (0.71-0.80)	2.51 (1.74-3.64)	0.53 (0.32-0.85)	4.78 (2.07-11.04)
Two consecutive values or three isolated values < 10th percentile

One value ≥ 3 cm below mean or three consecutive static or falling values
