Notes: Chi-square test is used in this table TCSS, Toronto clinical scoring system. a is for nerve symptoms; aX2, 44.249; p<0.001; b is for sensory examinations; bX2, 26.758; p, 0.003; c is for nerve reflexes; cX2, 76.631; p<0.001. Nerve symptoms; sensory examinations; and nerve reflexes can be considered different among the three groups.
