SB baseline | 26.3 (14.5) | 26.7 (17.3) | 3,658 (4,021) | 3,014 (1,915) | 50.2 (20.3) | 1.5 (1.7) |
SB hypoxia | 26.1 (13.9) | 33.0 (21.9) | 1,178 (1,168)* | 813.6 (705.7)* | 37.5 (14.2) | 1.8 (1.3) |
CB baseline | 23.5 (13.8) | 25.0 (17.0) | 1,132 (521.8) | 3,024 (2,099) | 62.9 (21.5) | 0.80 (0.88) |
CB hypoxia | 20.4 (9.4) | 34.3 (24.4) | 980.9 (354.1) | 765.4 (397.8)† | 37.5 (11.5) | 1.9 (2.1)† |
Values are means (SD); n = 9.
P < 0.05, significantly different from SB baseline.
P < 0.05, significantly different from CB baseline.
