Table 3. GEE comparisons of sensory and motor block of the sciatic nerve functions.

Results from the GEE analysis for BLA and adjuvants vs. 2% lidocaine are listed. A cumulative logistic ordinal model was fit with a linear and quadratic trend in time and time by group interaction (all significance tests use 2 df for group and group by time interaction).

Drug injected N Sensory block Motor block
0.375mM BLA 6 Chi-square=11.03, p=0.0040 Chi-square= 9.89, p=0.0071
0.375mM BLA + 2% lidocaine 6 Chi-square=11.23, p=0.0036 Chi-square=11.23, p=0.0036
0.375mM BLA + epinephrine 6 Chi-square=11.43, p=0.0033 Chi-square=10.54, p=0.0051
0.750mM BLA + 2% lidocaine 6 Chi-square=11.47, p=0.0032 Chi-square=11.44, p=0.0033
0.750mM BLA + epinephrine 6 Chi-square=10.03, p=0.0066 Chi-square=10.57, p=0.0051
