The Absolute Risk Reduction of 62 Thousand 500 Patient Years

The study enrolled about 25 thousand people, medium duration follo up of five years per patient. If estimate the difference of 32 events over a total of 62 thousand 500 patient years, you can plug these numbers into the calculator and that gives you an absolute risk reduction of zero point zero, three %. And that corresponds to a number needed to treat of about two thousand, 700 over five years. But based on the results of this study, i'm not convinced that prevention of auto disease is among them.
