Table 8. Ordinal Logistic Regression of Model A (BIS)
Test that all slopes are zero:P value < 0.001.
θ1–5= constants of the ordinal logistic regression model used in the prediction of the OAA/S levels 1 to 5; βremi = coefficient of the ordinal logistic regression model multiplied with the remifentanil (remi) effect-site concentration in the prediction equation; βprop = coefficient of the ordinal logistic regression model multiplied with the propofol (prop) effect-site concentration in the prediction equation; βbis = coefficient of the ordinal logistic regression model multiplied with the BIS in the prediction equation; SD = standard deviation.
