Unadjusted for other contributors, children in group 1, compared with those in the other three groups with higher WMn, had higher Full-Scale scores: groups 2 and 4 were significantly different from group 1 ( B -values = –11.93 and –23.80; p -values < 0.05 and 0.0001, respectively), whereas the finding for group 3 was in the same direction but did not achieve significance ( B = –8.92, p = 0.09).
