  • The analyses were weighted to account for selection in an internet survey. Because of weighting, the sum of participants and non-participants did not necessarily equal the number of total respondents. The numbers are no. (%), except for age. P values are calculated using an adjusted Wald test for age and χ2 tests for other categorical variables. The analyses of this table were for the purpose of simple description and did not account for multiple comparisons in the presentation of the p values. Comorbidities of hypertension, diabetes, asthma, coronary heart disease, stroke, COPD and cancer was defined as having a medical history of these conditions.
