Number (%) of subjects analysed by χ2 with continuity correction or Fisher's exact test, reporting odds ratios and 95% CI. The total number of asthma events within each group categorised (0, 1, 2, 3, . . .) and analysed using Mantel-Haenszel test for linear association (χ2 for trend). p values <0.05 significant.
