For models of AD specified as a time-invariant predictor of reproductive onset, unadjusted and adjusted hazard ratios (HRs) and 95% Confidence Intervals (CIs) are shown in Tables 2 and 3 for Cohort I and Cohort II, respectively. Results of AD modeled as a time-varying predictor of reproductive onset in Cohort II, along with time-varying control variables, are also shown in Table 3.
