Mortalities for infants divided by Era

	Era 1 1998–1999 (N=21)	Era 2 2000–2002 (N=30)	Era 3 2003–2004 (N=22)	Era 4 2005–2013 (N=119)	P Value
Unadjusted Count (percent)
Mortality incidence	5 (24)	8 (27)	1 (5)	22 (18)
Not repaired incidence	4 (19)	4 (13)	0 (0)	7 (6)
Survival for repaired incidence*	16/17 (94)	22/26 (85)	21/22 (95)	97/112 (87)
Multivariable Logistic Regression Adjusted Percent (95% Confidence Interval)**
Mortality incidence	23 (3–42)	25 (11–38)	6 (0–16)	10 (6–15)	0.20
Not repaired incidence	29 (9–50)	18 (4–33)	--***	5 (2–9)	0.01
Survival for repaired incidence	80 (59–100)	74 (59–88)	94 (84–100)	90 (85–94)	0.19

^*Survival (not Mortality) in repaired patient subgroup

^**Adjusting for candidate covariates gestational age, Caucasian race, primary repair (except not repaired outcome), and WHSR score positive, although only WHSR score positive remained in final models. P value is from a regression post-test comparison of the equality of the four adjusted percentages.

^***Zero percent after adjustment for covariates, so could not be estimated.
