Relationship between BIS and experimental noxious stimui.
| Median | IQR | Wilcoxon signed-rank test | |
|---|---|---|---|
| Moderate experimental noxious stimuli (X 1) | |||
| B 1 | 35.00 | 25.75–42.56 | P = 0.003 |
| X 1 | 40.00 | 28.50–46.00 | |
|
| |||
| Severe experimental noxious stimuli (X 2) | |||
| B 2 | 37.67 | 26.75–43.54 | P = 0.007 |
| X 2 | 40.00 | 28.00–48.25 | |
Changes in BIS in response to moderate (X 1) and severe (X 2) experimental noxious stimuli. Median and interquartile ranges are indicated for the 4 observation periods (B 1, B 2, X 1, and X 2). For the statistical difference between the two groups of participants, the Wilcoxon signed-rank test was used with P values.
