Figure 2From: Effects of simulated altitude (normobaric hypoxia) on cardiorespiratory parameters and circulating endothelial precursors in healthy subjectsRegression plot showing the correlation between changes in PB-EPCs from T0 to T1 and levels of PAO2 at T1 (r = 0.73; p = 0.03). PB-EPCs ΔT0-T1, peripheral blood endothelial precursors change from T0 to T1; PAO2 T1, Alveolar Oxygen Partial Pressure at T1.Back to article page
