Fig. 4

The difference between the HT and non-HT groups on M3 FWHM (Relative) and M3 MTT (Relative). The relative FWHM of the M3 segment was significantly lower in the HT group compared to the non-HT group (HT group: 1.00 vs. non-HT group: 1.75, p = 0.014). The relative MTT of the M3 segment was also lower in the HT group compared to the non-HT group; however, no significant statistical differences were observed (HT group: 0.83 vs. non-HT group: 1.00, p = 0.151).
