Asterisks denote the statistical significance of the comparison between high- and low-risk groups for each by Chi Square or T-test:

^***p < 0.001

^**p < 0.01

^*p < 0.05.

In the comparison of high-risk groups from each definition, p-values are shown or NS denotes the difference is not significant at the level of p<0.05.

CHS-A = Child Health Survey — Asthma.
