Error bars denote 95% confidence interval determined by bootstrap analysis of 1000 iterations. A) Age-dependent changes in the adenoids (Ad). A comparison of the Ad among the age groups revealed no significant changes. (347.55 � 12.52, 346.22 � 12.63, 355.41 � 14.51, 316.62 � 14.38, and 274.48 � 13.03 mm2 in the lower primary school, upper primary school, junior high school, senior high school, and young adult groups, respectively). B) Age-dependent changes in the tonsils (Tn). A comparison of the Tn among the age groups revealed no significant changes. (161.34 � 9.54, 152.82 � 9.35, 145.46 � 9.59, 127.64 � 8.48, 110.97 � 8.19 mm2 in the lower primary school, upper primary school, junior high school, senior high school, and young adult groups, respectively).
