Figure 1. Bland-Altman plots of rhythmic masticatory muscle activity indices for tested scoring montages.

Figure 1

Comparisons of tested scoring montages were made against PSG with bilateral masseter and temporalis muscle EMG traces. Solid line = the mean difference, dashed line = 95% LOA (maximum: the upper 95% LOA; minimum: the lower 95% LOA). EMG = electromyography, LOA = limits of agreement, PSG = polysomnography, 1M = PSG with unilateral masseter muscle EMG trace, 2M = PSG with bilateral masseter muscle EMG traces, 1T = PSG with unilateral temporalis muscle EMG trace, 2T = PSG with bilateral temporalis muscle EMG traces, 1C = PSG with unilateral chin EMG trace, 2C = PSG with bilateral chin EMG traces.
