Intersubject Delta BIS for both noxious stimuli.
| Median Delta Δ | IQR | Mann-Whitney U Test | |
|---|---|---|---|
| X 1 − B 1 (Δ1) | 1.7500 | −0.1875 to +6.3125 | P = 0.847 |
| X 2 − B 2 (Δ2) | 1.6650 | −0.4350 to +7.4150 |
Changes of BIS during each noxious stimuli. The median difference between BIS during moderate noxious stimuli (X 1) and baseline 1 (B 1) BIS and the difference between severe noxious stimuli (X 2) and baseline 2 BIS (B 2) were calculated as well as the IQR. The statistical difference between X 1 and B 1 (Δ1) and X 2 and B 2 (Δ2) was calculated with the Mann-Whitney U Test.
X 1: moderate noxious stimuli (40/100); B 1: baseline 1; Δ1: Delta 1; X 2: severe noxious stimuli (70/100); B 2: baseline 2; Δ2: Delta 2; IQR: Interquartile range.
