Relationship between consumption frequency† of full cream milk, milk products, butter and brown bread and prevalences of asthma and wheeze (n=2978)

Regression models“Ever asthma” (n=195)Recent asthma (n=145)Recent wheeze (n=442)
Values are presented as odds ratios (with 95% confidence intervals).
*p<0.05; **p<0.01.
†Odds ratios are shown for daily consumption and regular consumption v consumption less than once a week; for milk products and brown bread the prevalence of consumption less than once a week is less than 5% and therefore odds ratios are shown for daily consumption v all others.
