Excess NEC and NEC mortality incidence and cost for ELBW infants under suboptimal feeding condition

	400-1000g infants n = 24,149
Excess NEC cases under suboptimal feeding condition, (95% CI)*	928 (830, 1036)
Excess NEC deaths under suboptimal feeding condition, (95% CI)	121 (108, 134)
Medical NEC   Direct medical** cost   Indirect non-medical cost	$10.9 million ($9.2 million, $12.6 million) $269,068 ($226,584, $312,106)
Surgical NEC   Direct medical** cost   Indirect non-medical cost	$16.2 million ($13.6 million, $19 million) $267,587 ($224,546, $312,738)
Death	$1.5 billion ($1.3 billion, $1.6 billion)

^*The CIs represent the 2.5^th and 97.5^th percentiles

^**Direct medical cost is physician cost plus hospital cost (direct marginal cost + 15% overhead)
