Hi

Could you tell me what the underlined portion means?

Researchers have found that people who drink five or more cups of coffee a day have a risk of heart disease 2.5 times the average after corrections are made for age and smoking habits.

The risk of heart disease increases because of several factors, among them drinking coffee, smoking, and simply being older. The researchers have measurements related to all three of these factors, but they have subtracted out those that pertain to smoking and being older. That "corrects" the data for those two factors so that all that is left in the data is the set of measurements that have to do with drinking coffee.

  • The risk of heart disease increases because of several factors, among them drinking coffee, smoking, and simply being older.

  • Of course, if the researchers leave in the data for the other two factors, the risk of heart disease will be seen to be higher than it is just because of drinking coffee.

It means that you shouldn't worry your pretty little head over exactly what fudge factors the "researchers" used on their data, or even who they are. Just believe whatever they tell you.
