Table 4. Pearson Correlation Coefficients between BIS, Auditory Evoked Potentials, and Propofol Measured Concentration in Both Groups

BIS = bispectral index.

* Significantly different from all the auditory evoked potentials parameters (P < 0.00005 at α= 0.002).

† Significantly different from V and Nb amplitude (P < 0.0002 at α= 0.002).

‡ Significantly different from V latency (P < 0.001 at α= 0.002).

§ Significantly different from Nb latency (P < 0.0005 at α= 0.002).

∥ Significantly different from V amplitude and latency (P < 0.0005 at α= 0.002).

# Significantly different from Pa latency (P < 0.00001 at α= 0.002).
