Cox Proportional Hazards Regression Model Summaries for Squamous Cell Carcinoma (SCC) and Basal Cell Carcinoma (BCC) After Heart Transplant and Adjusting for Age and Sex

Variable	SCC		BCC
Variable	HR (95% CI)	P Value^a	HR (95% CI)	P Value^a
Posttransplant^b
Azathioprine use	0.93 (0.54–1.59)	.79	0.55 (0.31–0.97)	.03
Mycophenolate mofetil use	1.05 (0.57–1.94)	.86	2.74 (1.50–5.04)	.001
HSV infection	2.90 (1.24–6.77)	.01	3.38 (1.32–8.66)	.01
Nonskin cancer	1.80 (1.09–2.99)	.02	1.31 (0.70–2.43)	.40
HLA mismatches (≥1 vs 0)	0.53 (0.28–0.98)	.04	0.72 (0.36–1.45)	.36

Abbreviations: CI, confidence interval; HR, hazard ratio; HSV, herpes simplex virus.

P ≤ .05 was considered to be statistically significant.

Variables measured after transplant are time-dependent predictors.
