The study that Sciberras and colleagues argue is ideal for examining the attention deficit/hyperactivity disorder (ADHD) late birth date effect analyses the birth date distribution of 391 Victorian children, of which nine received medication.1 In contrast, our study2 reviewed de-identified data on the month and year of birth for all 5937 Western Australian children born between July 1998 and June 2008, who received at least one Pharmaceutical Benefits Scheme subsidised ADHD medication in 2013.
