TABLE 1.

Average numbers of genes induced in CD4⁺ T cells upon treatment with saturating dose of selected IFN-α subtypes^a

Level of upregulation	No. of genes induced at indicated level (avg across 3 donors) by IFN-α subtype:				P valueb
	1	2	6	14
≥2-fold	18	18	20	20	0.0417
≥3-fold	17	18	18	18	0.0625
≥5-fold	16	16	16	18	0.1667

^aThis analysis considers all 25 genes shown in Fig. 1B. The saturating dose used was 1,000 pg/ml.

^bSignificance testing was done using Friedman’s test (i.e., nonparametric RM one-way ANOVA).
