Table 3.

Correlation coefficients R, F test statistics and regression coefficients hHbR (10-7) of P1, N1, and P2 to predict HbR for each anesthetic and for combined anesthetics.

We do not report results for N2 in this table because N2 is 0 for four of the six anesthetics. Last column report P2 and N2 regression coefficients when both P2 and N2 are used as regressors. Results for HbO are similar and shown in the online supplemental material.
