The letter used to notate the probability of an event.
What is p?
The relative risk measure calculates a ratio of this in exposed vs. unexposed groups.
What is incidence?
This absolute risk measure is the difference in incidence in those exposed vs. unexposed.
What is risk difference / attributable risk?
Numeric value for no association between exposure and outcome.
What is 1?
ORs are used in this type of retrospective study.
What is a case-control study?
RRs can be used in this type of experimental study.
What is an RCT?
The attributable risk, where the incidence of MI is 5/1000 PY in smokers and 1/1000 PY in non-smokers.
Numeric representation for a negative association.
What is <1?
Using probability (chance) phrasing, this is the denominator in calculating an odds ratio.
What is the chance of something not happening?
Or

What is the incidence in unexposed?
Indicates the ______ of risk in a group of persons exposed to an important factor.
What is magnitude?
Numeric representation for a positive association.
What is >1?
This is the formula in calculating OR.
What is A*D / B*C?
OR
What is (A/B) / (C/D)?
