Erythropoietin (EPO) profile according to HIF1A genotype during the 8-hour exposure to 12.7% oxygen. EPO values are represented as a percentage of baseline values; CC (☐), CT/TT (♦). Values are the mean ± 1 SD. aWhole population significantly different from baseline (P <.001). bWhole population significantly different from the 4-hour time point. (P <.001).

Arterial oxygen saturation (Sao2) profile according to HIF1A genotype during the 8-hour exposure to 12.7% oxygen; CC (☐), CT/TT (♦). Values are the mean ± 1 SD. aWhole population significantly different from baseline at this time point (P <.001). bSao2 at this time point higher than at the 1-hour time point (P = .031).
