I was shocked to see something called Attibutable Risk Percent or Etiologic Fraction in a USMLEWorld CK question.
I did not encounter such thing in Kaplan notes or in FA or in my medical school or in High yield biostatistics book that I read for the boards.
For those of you who wants to know what is it.
It's calculated as follows
Risk in exposed - Risk in unexposed / Risk in exposed
or
RR-1 / RR
It tells how much percentage of the disease in the exposed population can be really attributed to the risk factor in question.
Now my question is, for such a rare complicated biostatistics equation and concept. Are we really going to see such questions in the real USMLE exam! If the answer is yes, then probably I will stop reading
