^ascore change means the score after radiotherapy minus the baseline score. Std standard deviation, MD median, MRM modified radical mastectomy, BCS breast conserving surgery, ns not significant (p > 0.10)
^aFor analyses at single level among ‘All’ patients, the paired t test p values are shown. However, p values of the median test (if equal zero) are 0.14 and 0.04 (not shown in table) for the anxiety and depression score change, respectively
^bfor analyses stratified by 2 study arms, p values from ANOVA are presented; meanwhile, p values from the non-parametric Kruskal-Wallis test are 0.09 and 0.45 (not shown in table either) for anxiety and depression score change, respectively
^cfor other analyses not stated above, p values from the Chi-square or Fisher exact test (if applied) are presented
