The figures in asthma at age 3 model are in odds-ratio (OR). Income at age 3 is treated as continuous. The 95% confidence intervals and p values are in brackets. Fully adjusted for sex, maternal age at childbirth, child birthweight, cigarettes per day during pregnancy and medical centre. SDQ-IH stands for Strengths and Difficulties Questionnaire sub-scores for child inattention-hyperactivity. Estimated using 50 imputed datasets.
