Table 4.

Effect of treatment strategy on long-term mortality among dextro-transposition of the great arteries hospital survivors during time periods after surgical correction that have proportional hazards.

	Unadjusted mortality HR (95%CI)	p-value	Adjusted mortality HR (95%CI)*	p-value
ASO (vs atrial switch):
Between 0 and 10 years	0.42 (0.12–1.51)	0.18	0.47 (0.13–1.71)	0.25
After 10 years	0.06 (0.01–0.47)	0.007	0.07 (0.01–0.52)	0.009

HR = hazard ratio, CI = confidence interval, ASO = arterial switch operation
