Comparison of flow meter and tracer kinetically modeled a stroke volume and b cardiac output at baseline and postxylazine infusion at 13.8 mg/kg min [19]. The equation in each chart represents the linear relationship between the measures, while the measure of fit is provided by the Pearson product-moment correlation coefficient (R). In all cases, unique colors represent individual animals at baseline (open symbols) and post xylazine (filled symbols) treatment
