Univariate comparisons between groups will be conducted using chi-square test for equal proportion (or Fisher's exact tests where numbers are small) and reported as numbers and percentages.
Univariate comparisons between the two study groups with respect to outcome measures and covariates at baseline will be conducted using Chi-square tests for categorical variables, Kruskal-Wallis tests for ordinal variables, and linear mixed models for continuous variables.

Comparisons between those who were victims of a violent offence (VVO) and those who were not victims of a violence offence (NVVO) were conducted using chi squared analyses and independent t tests as appropriate.
Univariate comparisons for male versus female, and those that had, versus those who had not, experienced alcohol-related non-consensual sex were conducted using chi square analyses because data were categorical.
Uni-variate analysis of the association between psychological distress and categorical data was conducted using Chi square (Fisher's two-sided exact test was used if numbers in the cells <5), while for continuous data Mann–Whitney test was used (non-normal distribution of data).
