15 signs YOU are one of the sleeping masses, from a mind-body-spirit perspective The best way to know that you are physically awake is to verify you are not sleeping. Look around.

In evaluating our risk estimates with those of various other studies, we sometimes use relative risks, either because a study with which we are evaluating our outcomes reported only relative risks or because comparing attributable dangers across countries with different background rates of intussusception could be misleading. To make sure that our results were robust, we used choice methods for age adjustment in post hoc analyses.
