<qa>  What is the only way in which patients who volunteer for this study will be treated differently from standardThe only ways in which patients who volunteer for this study will be treated differently from the standard of care are that they might receive more insulin than usual and they will have more blood drawn than usual. Giving extra insulin to these patients should not cause them harm, and may even help them. Since only about 5 tablespoons of extra blood will be drawn from each patient, this should not cause patients any harm.
