Association between defined clinical risk factors and HCMV reactivation and disease^a

Clinical parameter	Control vs HCMV positive	Control vs reactivation	Control vs disease	Reactivation vs disease
Acute GvHD	0.031	1.000	0.001	<0.001
Chronic GvHD	1.000	0.059	0.231	0.003
Corticosteroids (>2 mg/kg)	0.143	0.036	0.452	0.959
CD34+ cell selection	0.242	0.037	0.001	<0.001
CMV serostatus,b +/+	0.005	<0.001	0.250	0.390
CMV serostatus, +/−	0.006	0.005	0.046	0.552
CMV serostatus, −/+	0.007	<0.001	0.124	0.817

^aPatients in the control group did not show HCMV reactivation. Significant P values (<0.05) obtained by the Armitage trend test are underlined, and P values of <0.01 are in boldface. Positions of the SNPs in the respective genes were determined at http://snpper.chip.org/.

^bSerostatus of the donor/serostatus of the recipient.
