  1. Number of women in survival analysis and epigenetic aging analysis (EAA), and the proportion of dead at the end of the follow-up for each class when women were assigned to the most likely class based on highest posterior probabilities from the latent class solution. The number of live births (LB), age at the timing of the questionnaire in 1975 and age at exit (death or end of the follow-up) with their respective standard deviations (SD) are given for each class, calculated as weighted averages and standard errors based on class-specific posterior probabilities. The bottom row indicates sample sizes, averages and standard errors across all classes.
