Each column shows the characteristics of the sample used for each set of analyses (DHEA-related analyses, BRIEF and CANTAB analyses). The data are divided into 3 visits (as each child was followed longitudinally up to 3 times, every 2 years, for a total of 4 years), and the subdivisions ‘1, 2, and 3’ for each row represent each of these visits, except for the row ‘# Participants per # of Scans completed’, for which each row represents the number of scans completed. F=female; M=male
