    legend Figures between brackets indicate the percentage observed in the Antwerp district where, in view of the low numbers, significance was not reached. Overall χ2 test in male subjects, P = 0.002; overall χ2 test in female subjects, P = 0.800; overall χ2 test for male-to-female ratio, P = 0.024. Age distribution in background population for male and female subjects remained constant in both periods: ages 0–4 years, 11%; ages 5–14 years, 22%; ages 15–39 years, 67%. Completeness of registration compared to the Antwerp district with >90% ascertainment: 1989–1994, 36% for male patients vs. 31% for female patients; 1995–2000, 56% for male vs. 52% for female patients.
