摘要:
AbstractThe ascertainment of probands according to place of residence in hospitals or in the community has enabled our sampling to be representative of whole subpopulations of patients. Probands from psychiatric hospitals are characterized by biased clinical parameters. Our sampling procedure provides important preliminary results which appear to be contradictory to those produced by conventional sampling methods.
