  1. G allele: male G, female GG + GT; T allele: male T, female TT + GT
  2. Bold indicates significance
  3. *Chi-square test; the G allele is represented twice among females and only once among males, therefore, the total count of G alleles among all patients is 116, calculated as follows: (5 × 2 + 14) + (21 × 2 + 50) in the severe and moderate groups, respectively
