  1. Values reported as mean ± standard deviation, or median (range). All data are from the baseline visit except spirometry, which are reported from visit 2 (immediately before initiation of ICS). p- values are based on t-test or chi-square test for proportions unless otherwise noted.
  2. * In cases of multiple ethnicities, the lowest-numbered ethnicity from this list is reported: 1. Hispanic, 2. Black, 3. Pacific Islander, 4. Native American, 5. Asian, 6. White.
