Comparison of onset of CMV infection between patients with and without CMV disease

	ONSET OF CMV INFECTION (days)
	WITHOUT		WITH CMV
	CMV DISEASE		DISEASE
	Mean	Min-max	Mean	Min-max	p a)
Antigenemia pp65 b)	35	20-69	28	17-35	n.s.
CMV monitor c)	51	32-70	29	23-35	<0.029
CMV pp67 mRNA	51d)	37-69d)	28	17-35	<0.026

a) p = significance level for the difference between patients with and without disease, according to the Mann-Whitney U test; n.s.= not significant b) Antigenemia results are given as positive cells per 50,000 cells c) CMV monitor results are given as copies/mL d) Two patients without CMV disease were always negative by CMV pp67 mRNA. Thus onset of CMV infection by this assay only includes data for 3/5 patients without CMV disease.
