Question 3

Suppose a 1/2-pack-or-more-of-cigarettes-a-day smoker has a 200% increased risk of a certain type of serious facial skin condition. How do you interpret this? 

-You had better stop smoking, a 200% increase is a huge difference.

-You need to find out what the baseline risk is and what confounding variables were adjusted for before you can determine how serious this is for you.

-You should just continue smoking a ½ pack or more per day; no one could possibly come up with a valid statistic that measures this.
