  1. DBP, diastolic blood pressure; P, pulse; SBP, systolic blood pressure; SEM, standard error of the mean; SpO2, peripheral blood oxygen saturation
  2. P-value is based on the Kruskal Wallis-test. Significance is at the 5% level. Post hoc pairwise comparison were conducted by Mann-Whitney U test with the Bonferroni correction; different letters indicated a significant difference at the 0.00833 (0.05/6) level
