Results of two-way ANOVAs testing for effects of age and region on baseline measures of each dependent variable in sham irradiated, control rats (results of post-hoc tests provided in Figures 2, 3, 6 and 7).

Results of two-way ANOVAs testing for effects of age and region on baseline measures of each dependent variable in sham irradiated, control rats (results of post-hoc tests provided in Figures 2, 3, 6 and 7).双因素方差分析（two-way ANOVAs）的结果，用于检验假照射对照组大鼠各因变量（dependent variable）的基线测量指标受年龄与区域的影响效应，相关事后检验（post-hoc tests）结果详见图2、图3、图6及图7。
