Kruskal-Wallis test demonstrated significant difference between 2 age groups(P<0.01).There was an increase incidence of thickening, and thickening and nodule formation in 0-19, 20-year age group(P<0.01), but there was no gender difference between thickening and nodules.The data were analyzed by SAS6.12 Fisher's exact test and Kruskal-Wallis test.
