^*Compared with high-frequency group, P<0.05 (P-values were corrected for multiple comparisons using the Benjamini-Hochberg procedure to control the FDR ≤5%).

^†Compared with low-frequency group, P<0.05 (P-values were corrected for multiple comparisons using the Benjamini-Hochberg procedure to control the FDR ≤5%).

^‡ P-values were corrected for multiple comparisons using the Benjamini-Hochberg procedure to control the FDR ≤5%.

CMCT indicates central motor conduction time; FDR, false discovery rate; MEP, motor-evoked potential.
