Ages (yr)	33.1 ± 17.3	34.0 ± 19.0	48.3 ± 11.7	0.060
Gender				0.472
Male	11	16	5
Female	9	25	5

^aP < 0.05, indicates a statistically significant difference between group A and group B.

^bP < 0.01, indicates a statistically significant difference between group B and group C.

Unless otherwise indicated, data are number of patients.
