Figure 1From: Change in Hemoglobin Levels due to Anesthesia in Mice: An Important Confounder in Studies on Hematopoietic Drugs Illustration of the hemoglobin measurements (cross-over study). At blood samples 1–4, group A received anesthesia and group B served as control. At blood samples 5–9, group A served as control and group B received anesthesia. The mean values + SD are presented. *P < 0.05, **P < 0.01, ***P < 0.001.Back to article page
