Table 2. P Values for Predictor Variables in Logistic Regression Analyses of Unequivocal versus Nonresponse to Command
This table indicates the usefulness of Bispectral Index (BIS), spectral edge frequency (SEF), median frequency (MF), mean arterial pressure (MAP), and heart rate (HR) for awareness monitoring and displays their ability to discriminate between unequivocal responses to command (awareness, n = 139) versus nonresponses to command (unconscious, n = 887). In 10 consecutive analyses, displayed in separate columns, all combinations of three parameters were explored. In each analysis, two parameters were left out (×). All analyses were performed on the same database.
ns = statistically nonsignificant (P ≥ 0.05).
