Default randomized clinical trial

Hi all:

UW Q id: 7690 explanation says that the hazard ration for all cause mortality was 0.86, but the p value was not statistically significant( not less than 0.01), why it is 0.01, should be 0.05, right?

Thank you!

U brought up a good point .

I know one thing is that, for 99% confidence interval p=.01 and for 95% confidence interval p=.05

Most of the time p is used as .05

but I dont know why they have used p value as .01 here

though in this Question when HR is .86 the p value is .12 which is >.05
