	Unweighted Sample Size (N = 15339)	1,342	13,997

^aWeighted predicted percents of the population.
^bCurrently pregnant, asthma, cerebral palsy, epilepsy, stroke, intellectual disability (mental retardation), birth defect that causes limitations/difficulty.
with activities, lung/breathing problems, emphysema, heart disease, angina pectoris, myocardial infarction, coronary heart disease, blood disorders,
metabolic disorders, diabetes, weak/failing kidneys.
^cThis is the p value of the test of the association of the predictor by veteran status. Normally this would be a chi-square test, but accounting for the survey design (via the “svy” prefix) yields an F-test. The denominator degrees of freedom is 300 (reflecting the sample design) and the numerator degrees of freedom is the number of categories of the predictor minus 1.
