Cox PH regression analysis is a type of survival analysis alcohol-related approach, which accounts for the possibility that participants who have not yet experienced the event of interest may do so in the future. Under this approach, data up until the time of censoring (most recent interview) are used in the calculation of hazard ratios. The proportional hazard assumption, that risk remains constant over time, was tested with the Grambsch and Therneau test of the Schoenfeld residuals (Grambsch & Therneau, 1994). To correct for PH violations, age interactions were included to reflect specific risk periods. Therefore, when reporting the models with PH violations for predictor variables, hazard ratios are reported by risk period.
