Variable	HR (95% CI)	P Value
SCC
Nonskin cancer after transplant^a	2.03 (1.21–3.39)	.007
Age, 10-y unit	2.55 (1.90–3.42)	<.001
Cause (idiopathic vs all other causes)	0.59 (0.35–0.97)	.04
BCC
HSV infection after transplant^a	2.97 (1.16–7.59)	.02
Age, 10-y unit	1.81 (1.38–2.37)	<.001
Mycophenolate mofetil use after transplant^a	2.62 (1.42–4.82)	.002

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

Variables measured after transplant are time-dependent predictors.
