The significance of family type (whether from a multiplex (densely affected) alcoholic family or community family) and number of parents who smoke was greatest in the younger age ranges. Effects are measured in changes in logit(hazard) from baseline. When significant, SNP effects were about 1.0 for having two copies of the risk allele in the recessive genetic models, and the delta ERO effect was about 0.5 per standard deviation. When significant, the parental smoking effect was about 0.2 per smoker, the family type effect ranged from 1.0 to almost 2.0, and the gender effect ranged from about 0.5 to 1.0.
