-: Hi all, and welcome to module six.
In this module, we will continue our discussion
of Threats to Internal Validity.
We're going to start talking about confounding,
which is one of my favorite parts
of EPI methods to think about.
This is the first three modules
in which we'll discuss confounding,
getting increasingly complex as we go.
You might remember back to your discussion
of confounding an EPI one,
where you talked about how we're able to control or adjust
for confounding in the analysis phase of an EPI study.
In EPI one, we talked about adjusting
and controlling for confounding in terms of stratification.
However, there are more advanced methods
involving linear regression
that we're going to talk about starting in the next module.
Make sure that you're feeling really comfortable
and solid with the information this week
because we're going to be building on it
for the next few weeks.
So if you have questions
about what it means to be a confounder
or some of the basics of adjusting,
please reach out to me
before we move on to regression in the next module.
