Matched twin cohort: twins exposed vs. Given that dizygotic twins share equal genetic relatedness to the twin-sibling pairs, this dose-response pattern suggests that opposite sex monozygotic twins in Bedford genetic relatedness and early life attachment may contribute to the subsequent risk of psychiatric disorders among surviving twins after co-twin loss.
The Discussion section also includes other opposite sex monozygotic twins in Bedford that are not previously presented in the paper. Thank you for your comments. While we attempted to evaluate the influence of co-twin loss on the potential rise in psychiatric disorders, genetic confounding, namely the genetic susceptibility to psychiatric disorders and premature death shared within a twin pair, especially the monozygotic twins, is a concern in the present study.
Twin siblings are also the exact same age and the association could therefore reflect that the siblings have a closer relationship because they naturally have shared their lives with one another.

Here, we included all Swedish-born twins that lost a co-twin by death between and exposed twins , their full siblings, together with a group of age- and sex-matched unexposed twins who were randomly selected from the twin population and did not experience such a loss.
Sibling relationships from midlife to old age. The rate of cerebral palsy, for example, is six times that for singletons, according to one study. Suicidal behaviors in surviving monozygotic and dizygotic co-twins: is the nature of the co-twin's cause of death a factor?
