CB cold pressor test | 36.6 (18.4)†‡ | 40.7 (20.9)‡ | 607.3 (332.6)† | 2,305 (2,000) | 62.6 (29.5)† | 2.3 (6.0) |
Values are means (SD); n = 11.
P < 0.05, significantly different from SB baseline.
P < 0.05, significantly different from SB cold pressor test.
P < 0.05, significantly different from CB baseline.
