A set of training materials for professionals working in intervention epidemiology, public health microbiology and infection control and hospital hygiene.
The last sentence of the cohort study section ("Therefore, in this example, age is not a confounder of the relationship between magnetic field exposure and breast cancer.") seems to be in error (should read: gender not confounder for vaccination status and disease).
I am not sure as to which section this comment applies. Is this a different chapter?
Your comment is correct, however it was placed by the wrong chapter. Your remark is about an error in the chapter on Confounding, not on Causal Inference.
Thanks a lot for your remark, I have modified the content accordingly. I want to invite you to make modifications and improvements directly to the text as well, This is why it is a WIKI.
