Haemoglobin concentration at BL and Hbcrit. Grouped boxplots of the arterial haemoglobin concentration (g · dL−1) at BL and Hbcrit. The results are presented pairwise as boxplots (median line) with whiskers (min to max). Data from the clonidine group are coloured white, and saline group data are dark grey. No difference was demonstrated between the groups. BL (baseline, premedication); Hbcrit (critical haemoglobin concentration). Exchangeable blood volume (EBV). Boxplots of the exchangeable blood volume (mL · kg−1) until Hbcrit was reached. The results are presented pairwise as the median and quartiles (Q1-Q3). No differences were demonstrated between the groups. Hbcrit (critical haemoglobin concentration)
