VEGF and ET-1 concentrations in plasma. Normoxic and hyperoxic study groups are illustrated with white and grey box plots, respectively. a VEGF concentration in normoxia (n = 8) and hyperoxia (FiO2 1.0) (n = 8). b ET-1 concentration in normoxia (n = 8) and hyperoxia (n = 7). Data are expressed as vertical box plots with median, 10th, 25th, 75th, and 90th percentiles. Asterisk displays a significant change between study groups, p < 0.05
