here is my code: proc freq data=table3_3_a;
tables treat*DU1ORRES3 / riskdiff(margin=0.1 noninf) alpha=0.025;
run; and here is the result of the freq as i know, if the lower 95% cl is smaller than the non-inferiority margin(-0.1161<-0.1), then the p value will be bigger than 0.05 and the null hypothesis should be rejected, but the p value here is smaller than 0.05, i think i might missing something, could you help me understand better?
