The mean ± SD age for all patients was 37.2 ± 16.1 years (median, 35 years; range, 0.75 to 88 years). The mean ± SD age for clustered patients was 32.2 ± 13.1 years (median, 29.5 years; range, 3 to 67 years). The mean ± SD age for nonclustered patients was 38.9 ± 16.7 years (median, 36 years; range, 0.75 to 88 years). (P = 0.002).
