  1. Intergroup differences in the ratio of male/female, smoker/nonsmoker, alcohol consumer/non-alcohol consumer, and medicated/non-medicated were assessed by chi-square tests. Independent differences in each of the other variables between groups were assessed by analyses of covariance, after adjusting data on age for sex and the others for age and sex. *P < 0.05 versus JSD < 0.4.
