Table 3. Pearson Correlation Coefficients between BIS, Auditory Evoked Potentials Parameters, and Sedation in Both Groups

BIS = bispectral index.

* Significantly different from all the auditory evoked potentials parameters (P < 0.0000005, at α= 0.002).

† Significantly different from V amplitude and latency, Pa and Nb amplitudes (P < 0.001 at α= 0.002).

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

§ Significantly different from V amplitude (P = 0.0003 at α= 0.002).

∥ Significantly different from V and Nb amplitude (P < 0.00095 at α= 0.002).
