One study shows that 30 minutes of exercise 5 times a week can
reduce your risk of squamous cell carcinoma of the
skin, p=0.001. (Let's pretend this is true). What does this
Well, let's start by asking the question, how IMPORTANT is it
that you reduce your risk of SCC of the skin, and how MUCH does
exercise reduce that risk? If the effect of exercise is associated
with a relative risk reduction of 1% in your lifetime risk of SCC,
is that enough to get you to spend 1 week of your life each year on
In this week's "I wonder" series, Dr. Ali Hamedani joins Jim
Siegler to discuss the difference between statistical significance
and clinical importance, how to interpret p-values, and exactly
what kinds of conclusions you should draw from clinical
