Percentage of naïve CD4⁺ T cells expressing CD31 in peripheral blood at 4, 24, 48, and 72 h

Cell source	% (IQR) naïve CD4+ T cells in peripheral blood expressing CD31 at:				Difference in % (IQR) naïve CD4+ T cells in peripheral blood at 4 ha from the following time points:
	<4 h	24 h	48 h	72 h	24 h	48 h	72 h
HIV− subjects (n = 17)	51.5 (44-57)	53.2 (45-62)	54.8 (42-62)	57.7 (48-65)	−1.8 (−4.0 to 1.0)b	−3.3 (−7.0 to −1.0)c	−6.2 (−9.0 to −4.0)d
HIV+ subjects (n = 37)	49.5 (41-57)	51.2 (41-59)	52.7 (42-60)	55.0 (45-64)	−1.6 (−3.0 to 2.0)e	−3.1 (−5.0 to 1.0)f	−5.4 (−8.0 to −2.0)d

^aPaired comparisons with the results for freshly isolated peripheral blood at <4 h were done by the paired t test.
