Familial concordance for age at menarche: analyses from the Breakthrough Generations Study.

abstract：:Recurrence risk provides information on the heterogeneity of risk in the population, and thus is useful for aetiological studies. While recurrence risk is observable in many areas of epidemiology, it is particularly accessible in the study of perinatal events. High recurrence rates of pregnancy problems suggest geneti...
