The changes in average RIF-1 tumor pO2 before and after split dose radiation. (a) 0 Gy, n = 18, (b) 10 Gy +10 Gy at 0/24 hr, n = 42, (c) 10 Gy +10 Gy at 0/48 hr, n = 19. Arrows indicate the time of irradiation. * p< 0.05, ** p < 0.01, compared with baseline tumor pO2 in the same group (paired t-test).
