| Age groups (years) | PWS Patients (n = 569) | Glaucoma in PWS Patients (n = 110) | Statistic | P* | ||||
|---|---|---|---|---|---|---|---|---|
| Male, n (%) | Female, n (%) | Total, n | Male, n (%) | Female, n (%) | Total, n | |||
| Under 4 | 214 (51.0) | 206 (49.0) | 420 | 47 (61.8) | 29 (38.2) | 76 | χ2 = 4.403 | 0.036† |
| 4–18 | 58 (58.6) | 41 (41.4) | 99 | 15 (51.7) | 14 (48.3) | 29 | χ2 = 0.796 | 0.372† |

*P value was obtained by comparing the PWS with glaucoma patients’ gender constituent ratio to the PWS patients without glaucoma affected; †Chi-square test; ‡Fisher’s exact test. PWS: Port-wine stain.
