aNonnormally distributed data are shown in quartiles (25%|median|75%). bFriedman test and Dunn test; P values have been adjusted for multiple comparisons by the Bonferroni correction; For P values larger than or equal to 1 after the correction, they are displayed as 1.000; significant differences (P < .05) are underlined. EMG = electromyography, PSG = polysomnography, RMMA = rhythmic masticatory muscle activity, 4MT = reference standard, PSG with bilateral masseter and temporalis muscle EMG traces, 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.
