Causal effects on BIS values and correlations among exogenous variables with standardized path coefficients based on the final path analysis.

CI, Confidence interval; SE, Standard error; BIS, Bispectral index; MAP, Mean arterial blood pressure; SPC, Sevoflurane plasma concentration; HKT, Hematocrit; CPB, Cardiopulmonary bypass; Interpretation of standardized path coefficients β according to product-moment correlation: >.1 = weak effect; >.3 = moderate effect; >.5 = strong effect.
