Figure 2:

Relative risk by median risk exposure for 40-year-old women. A) The sliders reflect age (range 20–80 yr), exposure level for each risk (range 10th–90th percentile, reflecting percentile exposure level in the total population) and sex-specific algorithm (male, female). B) Point estimate (red dot) and 95% confidence interval (blue line) of 5-year relative risk of cardiovascular event by exposure variable. Reference group for continuous variables = lower number from the exposure slider (10th percentile in this example), with the exception of smoking, where reference group = nonsmoker. Reference group for categorical variables = pink dot. C) Visualization for impact of age interaction and exposure level on relative risk for selected exposure: y-axis = relative risk, x-axis = age or percentile exposure. In this example, selected exposure = current smoker, age = 40, percentile exposure for pack-years = 50th. Blue line represents range of relative risk by age or percentile of exposure.
