Comparative analysis of Flatness with bilateral MCs under different NVC conditions. (A) No NVC on both sides. The MC of the affected side of the left PTN without bilateral NVC was lower than that of the unaffected side (0.39 ± 0.04 vs 0.42 ± 0.04, P < 0.051), the MC of the affected side of the right PTN without bilateral NVC was lower than that of the unaffected side (0.35 ± 0.03 vs 0.39 ± 0.04, P < 0.05). (B) NVC on both sides. There was no significant difference between groups. (C) NVC on affected side and no NVC on unaffected side. There was no significant difference between groups. (D) NVC on unaffected side and no NVC on affected side. There was no significant difference between groups.*P < 0.051; ** P < 0.05; ns:P > 0.05; NVC: neurovascular contact;L: Left; R: Right; AS: Affected side; US: Unaffected side.
