Fig. 6.

Number of motor units contributing to the CMAP (open circles, lefty-axis) and the recCMAP (filled circles, right y-axis) with time after nerve repair with direct suture (n = 4 nerves). Each data point represents the mean (± SEM) of the measurements for that time point. Linear curves were calculated from the least squares method. n, Number of time points used to calculate the curve; r, correlation between time and number of motor units; p, statistical significance of the correlation (two-tailed test); ns, nonsignificant.
