what does a + b represent where exposure represents a medication?
those people in the study that were given the medication
what does c + d represent in terms of a study involving a medication?
c + d are those participants that did not get the medication
what does a + c represent in terms of a study involving a medication?
those participants that developed the outcome of interest
what does b + d represent in terms of a study involving a medication?
those participants that did not develop the outcome of interest
what does a + b + c + d represent?
everyone that was in the study

I(E) will represent the risk of developing the outcome associated with the exposure group.

how would you write out the equation:
I(E) = a/ (a + b)
I(U) will represent the risk of developing the outcome associated with the un-exposed group.
I(U) = c / (c + d)
prospective studies are incident studies.

incidents are (new/existing)

so our starting population (can/cannot) have the disease
new
cannot
what is the definition for relative risk?
The risk in the EXPOSED GROUP relative to the RISK in the UNEXPOSED
what is the formula for relative risk:
(see figure)
in a case control study, we are starting with cases, in other words, the population is ...

this is a (prospective/retrospective) study
already sick
retrospective
in a Retrospective or Case Control study, the people are already sick, they are belong to squares ...

we need to find people to put into the control group and they will be placed in squares ...
a + c
b + d
for a retrospective study, what is the calculation for odds ratio:
(a/c)/(b/d) = (a*d)/(b*c)
what would you use for a
1. Prospective Study
2. Retrospective Study

odds ratio
relative risk
1. relative risk
2. odds ratio
calculate either the relative risk or odds ratio which ever is appropriate for this study
(see figure)
this is a prospective study
for this retrospective study, calculate either the relative risk or odds ratio which ever is appropriate for this study
