reference category
2
Q
how do we compare when looking at occurrences in different populations
A
ratio
difference
3
Q
define exposure
A
factor associated with an outcome of interest
4
Q

A
possible result that might stem from exposure
5
Q
what are common measures of association
A
risk ratio
rate ratio
odds ratio
6
Q
Risk ratio equation
A
RR = CI of disease in exposed / CI of disease in unexposed
7
Q
Rate ration equation
A
IRR = IR of disease in exposed / IR of disease in unexposed
8
Q
Odds
A
of cases with disease / # of cases without
OR
X / (1 - X) *X being probability
9
Q
Odds ratio equation
A
odds (given x) / odds (given no x)
