↵* Mean difference (95% CI).
↵† Behavioural outcomes were assessed using the Strengths and Difficulties Questionnaire (SDQ) completed by parents (n=162). Children with scores >90th percentile of a comparison group of 153 classmates were classified as at risk for clinically significant difficulties in each domain and overall for total difficulties.
