2×2=4
2×3=6
2×4 =8
2×5 =10
2×6=12
2×7=14
2×8=16
2×9=18
2×10 = 10

Interpret data found in a 2 x 2 table
Compare and contrast the 4 most common types of epidemiologic studies: cohort studies, randomized controlled trials, case-control studies, and cross-sectional studies
Calculate and interpret relative measures of association (risk ratios, rate ratios, odds ratios)
Explain which measures are preferred for which study designs and why
Discuss the differences between absolute and relative measures of association.
Before getting into study designs and measures of association, it is important to understand the notation used in epidemiology to convey exposure and disease data: the 2 x 2 table. A 2 x 2 table (or two-by-two table) is a compact summary of data for 2 variables from a study—namely, the exposure and the health outcome. Say we do a 10-person study on smoking and hypertension, and collect the following data, where Y indicates yes and N indicates no:
Table 4-1
Participant # Smoker? Hypertension?
1 Y Y
2 Y N
3 Y Y
4 Y Y
5 N N
6 N Y
7 N N
8 N N
9 N Y
10 N N
You can see that we have 4 smokers, 6 nonsmokers, 5 individuals with hypertension, and 5 without. In this example, smoking is the exposure and hypertension is the health outcome, so we say that the 4 smokers are “exposed” (E+), the 6 nonsmokers are “unexposed” (E−), the 5 people with hypertension are “diseased” (D+), and the 5 people without hypertension are “nondiseased” (D−). This information can be organized into a 2 × 2 table.
