Adjusted odds ratios (OR) and 95% confidence intervals (CI) of offspring autism spectrum disorders (ASD) by parental asthma when comparing cases with unrelated controls, half‐cousin, full‐cousin, and maternal/paternal half‐sibling controls nested in the birth cohort. Panels (A and B) show the estimates for maternal asthma and paternal asthma separately, after adjusting for parity, maternal smoking during pregnancy and civil status at year of child birth, country of birth and age at child birth for mothers and fathers, highest education between parents, and maternal body mass index at first antenatal visit. The asterisks were used to indicate statistically significant associations
