p value in 95% CI <0.05 SO THE relative risk is
less than 5 % WILL DEVELOP DEMENTIA THATS ALL
Thankyou.
The answer was 0.03
Do you think it was a question in which you had to find the answer by principle of exclusion.
As other option was 0.05 and rest were more than that
Alsi as rr isless than 1 , so patient will not develop dementia?? Or am I wrong?
WELCOME in this exam expect anything but it is all about training do questions boost ur mind.the usmle people who make questions they are not medical student or medical graduate
rr lesS than 1 decrease risk. more than one increase risk …….and CI shouldn't EQUAL 1 OTHERWISE WONT REJECT NULL HYPOTHESIS AND THERE IS NO ASSOCIATION NEITHER INCREASE OR DECREASE
