Table 1 Summary statistics for the patient level data (N = 1001)

Variable	Variable type	Mean	Median	Standard deviation	Range
LOS	Discrete	20.1	10.0	25.4	(1,227)
BWEIGHT	Continuous	2418.0	2335.0	939.8	(360, 5493)
GESTAGE	Continuous	34.6	34.0	4.0	(23, 42)
SNAPDOL1	Discrete	8.2	0.0	13.1	(0, 103)
SNAPDOL3	Discrete	5.0	0.0	10.4	(0, 86)
MAIN1	Continuous	484.8	417.0	314.0	(0, 2139)
MAIN7	Continuous	661.2	607.0	361.3	(0, 2486)

LOS represents a patient’s length of stay in the NICU, BWEIGHT represents a patient’s birth weight in grams, GESTAGE denotes a patient’s gestational age in weeks, SNAPDOL1 represents a patient’s SNAPPE score recorded after 1 day spent in the NICU, SNAPDOL3 represents a patient’s SNAPPE score recorded after 3 days spent in the NICU, MAIN1 represents a patient’s MAIN score recorded after 1 day spent in the NICU and MAIN7 represents a patients MAIN score recorded after 7 days spent in the NICU. The smaller the SNAPPE and MAIN scores, the physiologically healthier the child.
