- aA two-sided t-test was used to compare the age of men and women. Two-sided chi-square tests were used for all other comparisons. For variables with two response categories, a single chi-square test was used. For variables with three or more response categories, a separate chi-square test was used for each response category. P-values less than 0.05 are written in boldface
- bTwo-sided Fischer’s exact test was used because at least one cell had an expected cell count below 5
- cThe percentages add up to more than 100% because more than one alternative could be chosen
