  1. *Trauma events is a measure of the exposure of the directly exposed individuals (1980 F1 and 2011 F2 and 2011 F3 Older Child). In Prenatal and Germline exposure groups, the Trauma events score measures the exposure of the directly exposed ancestor of each individual in these groups. The Trauma events score varies according to the directly exposed individuals that were included in each exposure group in the table.
