Which indicator is used to compare the risk of suffering a given disease when a given exposure is present or absent?
Odds Ratio
What can be used to assess the association between having been exposed to a given condition and suffering a given disease?
Relative Risk
What does Population Attributable Risk measure?
The proportion of disease cases in the population that could be attributed to the exposure
Under what conditions are Relative Risk, Odds Ratio, and Attributable Risk estimable?
In both experimental and observational studies
Which measure is used to compare risks under different study designs?
Prevalence Ratio
What is the proper measure to compare the risk of a disease between two exposure groups in cohort studies?
Risk ratio
What is the main purpose of Attributable Fractions?
To estimate the proportion of disease cases due to exposure
What is the interpretation of RR = 1.50 in a cohort study?
The disease risk is 50% higher in the exposed group
What is used to estimate P(D|E) in case-control studies?
Odds ratio
Which transformation of probability is used to compare the prevalence of exposure in case-control studies?
Odds
What measure of association is used in cross-sectional studies to compare the prevalence of disease between two exposure groups?
Prevalence ratio
What does an OR = 1.71 indicate in a case-control study?
The odds of having the disease among exposed are 71% higher than among non-exposed
When comparing two groups, why could using ratios lead to different results than using differences?
Ratios and differences work in different metrics
What can happen if PR1 > PR2 while PD1 < PD2 in a given study?
It suggests inconsistency between different measures
Why are ratios more widely used than differences in studies?
Ratios are more interpretable than differences

Risk difference
What does an OR = 1 indicate in a case-control study?
There is no association between exposure and disease
