Coefficients for the smokers with asthma are depicted before the slash; the coefficients for the smokers without asthma are depicted after the slash.

The ‘Independent Variables’ in the left columns are the ones denoted in the upper right columns. ^†p <.10, *p <.05, **p <.01, ***p <.001.

Some paths were not significant among adolescents with asthma whereas they were significant among adolescents without asthma, and vice versa. Although this may seem as a difference, please note that significance of estimates is dependent on sample size.
