Dear Statalist,
I have 2x2 data from a clinical trial:
Event vs no event x treatment vs control.
The hypothesis is non-inferiority with a margin of 12%.
I use
- cs event treatment, limit(90) -
to obtain the risk ratio and 90% CI. But is there any way within Stata to obtain the 1-sided alpha for non-inferiority?
Thanks for considering,
Thomas
