  1. aDifferences in shape of bilateral SPG between CH and non-headache healthy controls were analyzed by chi-square test, p < 0.05 was considered statistically significant
  2. bDifferences in shape of SPG between pain-side and non-pain side of CH patients were analyzed by chi-square test, p < 0.05 was considered statistically significant
