  1. *Applying Bonferroni’s correction for the 12 multiple comparisons (3 groups compared to propofol only group at 4 time points) results in α = 0.05/12 = 0.0042. All 12 comparisons achieved statistical significance as p ≤ 0.001 < α = 0.0042 for each of the above comparisons
  2. **These differences are correct to 2 decimal places. Because of rounding to two decimal places in Fig. 2, they differ by 0.01 from those that would be calculated using Fig. 2
