Table 4.

Comparing duration of MV and PICU stay according to serum phosphorus level.

Variable	Normophosphatemia (N = 3)		Hypophosphatemia (N = 15)		MWU test	P value
Variable	Median	Range	Median	Range	MWU test	P value
Duration of MV (days)	5.0	4–5	8.0	4–19	2.39	0.017 (S)
	Normophosphatemia (N = 19)		Hypophosphatemia (N = 31)		MWU test	P
Duration of PICU stay (days)	8.0	7–13	10.0	7–20	3.82	<0.001 (HS)

MV, mechanical ventilator. PICU, pediatric intensive care unit. HS, highly significant.
