*Not reassessed, but taken from measurement 2 (no further blood withdrawal), #since the beginning of hemodilution procedure (for calculations see Materials and Methods section), §P < 0.05 vs. measurement 1, ¶P < 0.05 vs. measurement 2, ║P < 0.05 vs. measurement 3, ‡P < 0.05 vs. both other measurements, †P < 0.05 vs. basal and other measurement, respectively. For further details on the statistical analysis see Appendix 1. Values are mean ± standard deviation (SD). BV, blood volume; ESL, volume of the endothelial surface layer; ; HK_LV, large vessel hematocrit; HK_WB, whole body hematocrit; PV, plasma volume; RCV, red cell volume.
