PROC TABULATE DATA=respiratory;
CLASS status treatment CENTER;
VAR  AGE;
TABLE (treatment='' ALL)*(status='' ALL) ,AGE='age'*(CENTER ALL)*(colpctsum mean sum)
/box=[label="treatment & status  by age"    style=[fontstyle=italic]];
RUN;

标准差（又称标准偏差、均方差，英语：Standard Deviation，缩写SD）稍微改动一下 应该可以得到楼主想要的结果
PROC TABULATE DATA=respiratory;
CLASS status treatment CENTER;
VAR  AGE;
TABLE (treatment='' ALL)*(status='' ALL) ,AGE='age'*(CENTER ALL)*(N mean STD)
/box=[label="treatment & status  by age"    style=[fontstyle=italic]];
RUN;

我想用report过程实现而不是tabulate过程。谢谢啦，币给你了，辛苦了
