  1. Normally distributed data is reported in mean +/− standard deviation. Non-parametric data is reported in median with interquartile range in parenthesis. Reported with reference intervals (RI) calculated using the Robust method reported as 90% confidence interval in accordance with American Society for Veterinary Clinical Pathology guidelines. All values were compared to each other. Values that are significantly different (adjusted P < 0.05) than all other time points are marked as follows: adenotes significance when compared to T0, + denotes significance when compared to T1, bdenotes significance when compared to T4
