Table 3.

Effect of treatment strategy on overall survival of dextro-transposition of the great arteries patients 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 1 month	1.39 (0.81–2.37)	0.23	1.62 (0.93–2.85)	0.10
Between 1 month and 10 years	0.45 (0.12–1.64)	0.23	0.52 (0.14–1.90)	0.32
After 10 years	0.06 (0.01–0.46)	0.007	0.07 (0.01–0.52)	0.009

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