Hi everyone,
and welcome to the fourth module of Epidemiology 2.
This module focuses on measures of association,
so that's things like risk ratios, attributable risk,
and odds ratios.
We first review what we did in Epi 1,
looking at these measures
and when they are appropriate to use
and then we'll look more deeply
into the mathematical development of these measures
and also the relationship between the measures,
particularly the relationship between risk and odds.
This will be very important for us as we go forward.
If these measures have been tricky for you in the past
or if it's been a while
since you've really thought about them,
I encourage you to go back to your Epi 1 textbook
and notes to refresh your memory
before diving into this week's material.
If I can help in any way with this
please don't hesitate to let me know.
Have a good week and take care.
