Table 2 Features ranked by feature importance, permutation importance or absolute coefficient values for outcome PaO₂/FiO₂ prediction

	LR	RF	GNB	XGB	Mean rank
PaO₂/FiO₂ ratio 3 h last	73	73	73	73	73
last FiO₂ 2 h slope	72	70	64	70	69
PaO2/FiO₂ ratio 2 h	65	72	70	44	62.75
Ventilatory ratio 8 h slope	69	49	61.5	66	61.375
PaO₂ 2 h	61	71	72	36	60

The top parameters scored consistently high across the various models which may possibly indicate some predictive capacity for these features
