Statistical analysis 
Data was cleaned using Microsoft Excel and further analysed in IBM SPSS 26. Invalid or missing answers were corrected or deleted by evaluating women’s comments or subsequent responses throughout the evaluation. If contradictory information was provided in the evaluation form, e-mail correspondence was checked in the WoW database for the original answer. Descriptive statistical analysis was performed on demographic information and main outcomes. For questions with multiple answers, new categories were created, and variables were re-coded into binary variables in accordance with previous studies(11, 16, 19, 21, 22). 7 age categories were created; <20, 20-24, 25-29, 30-34, 35-39, 40-44, ≥45 based on previous literature and for the purposes of summarising the data, but age was included as a continuous variable in logistic regression analysis(21). Evaluations from Ireland and Northern Ireland were grouped, in accordance with previous research using WoW data(21). A binary logistic regression analysis was performed to test associations further. Four regressions were run for the total sample and year, adjusted for age. The year 2009 was set as the reference category.
