^aThe odds ratio both for medically significant wheezing versus mild wheezing or no wheezing and for any wheezing versus no wheezing.

^bIntercept for the cumulative odds of medically significant wheezing versus either mild wheezing or no wheezing.

^cIntercept for the cumulative odds of any wheezing (medically significant or mild) versus no wheezing.
