  1. aPositive values indicate improvement, note: to account for differences in labeling:
  2. Nicalert change = baseline − final (less nicotine exposure), and Asthma Life Quality change = baseline − final (increased quality of life); but asthma control change = final − baseline (improving control), asthma knowledge change = final – baseline.
  3. bCategorical variable with 6 possible, higher values = increased exposure.
  4. cMean (SD) for continuous variables, count/total (%) for discrete variables.
  5. d9/1/13 through 5/25/17.
