Results for the Event History Analysis on age at first marriage and age at first birth in relation to early mortality exposure for the Krummhörn, the Finnish, and the Québec population.

Results are shown for both the iwt-models (controlling for covariates showing an interaction with time if the proportionality assumption is not met) and the stratified model (stratification by family ID to control for family membership). The effects of the included covariates are reported as hazard ratios (HR). Sex is coded as 0 = female and 1 = male. For complete results of the models including all covariates see the supporting information (tables S1, S2 and S3).iwt = controlling for covariates showing an interaction with time.Significance: *** p
