Modest familial risks for multiple sclerosis: a registry-based study of the population of Sweden.

ABSTRACT: Data on familial recurrence rates of complex diseases such as multiple sclerosis give important hints to aetiological factors such as the importance of genes and environment. By linking national registries, we sought to avoid common limitations of clinic-based studies such as low numbers, poor representation of the population and selection bias.
