Fig. 8. Summary of concentration–response slopes for selected parameters in the study, as measures of the effect-specific potency of sevoflurane. Mean values and confidence intervals shown are from the second column in tables 1 and 2, normalized to the baseline values (column 5 in the tables) for easier comparison in the graph. If the boxes do not overlap with the line of zero, the effect is significant, as indicated in gray. For all parameters shown, propofol did not show a different effect compared with sevoflurane (see column 3 in tables 1 and 2).
