What if the confounder is continuous? We can also adjust for a linear term in age (or other confounding variable) in a logistic regression model: Example:

from 1.0 than the risk ratio. For these and other reasons many people have called for researchers to report risk ratios instead of odds ratios (for example
In the above example after the odds ratio is corrected (where. OR=3.27 and P0 =0.24)
