* Patients were sampled from 11 academic medical centers in nine states (University of Washington [Washington], Oregon Health and Sciences University [Oregon], University of California Los Angeles and Stanford University [California], Hennepin County Medical Center [Minnesota], Vanderbilt University [Tennessee], The Ohio State University [Ohio], Wake Forest University [North Carolina], Montefiore Medical Center [New York], Beth Israel Deaconess Medical Center and Baystate Medical Center [Massachusetts]).
† Other non-Hispanic included two persons who reported being American Indian/Alaska Native, 25 Asian, three Native Hawaiian/Other Pacific Islander, and 18 Other; five reported both Asian and Other for race. Other race group combined because of comparatively low numbers in these groups compared with other race/ethnicity groups.
§ Excluding 16 (5%) patients who did not answer questions about underlying medical conditions; for those who answered questions about underlying conditions, some respondents were missing data on congestive heart failure (one), obesity (three), rheumatologic/autoimmune conditions (one), neurologic conditions (one), and psychiatric conditions (two); denominators used to calculate proportions of respondents with individual underlying medical conditions excluded patients who have missing data for the condition.
¶ Unknown for 17 (14 outpatients and three inpatients); among those who had ever used tobacco products, one did not state whether they were a current tobacco user.
** Unknown for 19 (16 outpatients and three inpatients).
