the data was statistically not significant in either case-control or family-based analysis for 11R, 10R, 9R and 7R; the 6R allele showed significantly lower frequency in ADHD case group but ETDT analysis failed to show any bias in transmission; the 5R allele showed significantly higher occurrence in ADHD case group but ETDT analysis failed to show any bias in transmission
