The time to emerge from isoflurane (time to recovery of consciousness) is not significantly correlated with different measures of suppression. (a) The cumulative percentage of the recording spent in suppression (R²=0.03, P=0.40); (b) the longest period of continuous suppression (R²=8×10⁻⁴, P=0.89); (c) the number of transitions between suppression and non-suppression (R²=0.02, P=0.51); and (d) the cumulative percentage of the last 15 min of the recording before isoflurane is discontinued spent in suppression (R²=0.02, P=0.44).
