Flashcards in Lesson 7: Categorical Outcomes, Odds Ratio & Risk Assessment Deck (11):
A mathematical comparison between two numbers. The numerator is included in the denominator.
Frequency distributions of multiple variables represented in a single table
The number of ways an event can occur relative to the number of ways an event cannot occur; does NOT include the numerator in the denominator [ex: 4/6 while the proportion would be 4/10]
The odds of exposure among diseased (cases) vs non-diseased (controls)
The likelihood of developing the disease/outcome given that one is exposed divided by the likelihood of developing the disease/outcome given that one is non-exposed
Measure of disease association
The magnitude of the effect of an exposure on an outcome
The odds ratio is most commonly presented in a ..
contingency table, which displays the frequency distribution of multiple variables in a single table
Which variable from this unit is a measure of effect size? That is, it determines the strength of the relationship between two variables.
If relative risk = 1..
there is no association between risk in exposed and risk in non exposed
If RR (relative risk) is greater than 1..
there is an increased risk for those exposed
