The reference category for the model with covariates is an individual who identified as right-wing, achieved a high school or less education, was not married, was not an immigrant, did not have any military experience, did not engage in any previous criminal violence, and had an exposure event that occurred in the 2010s. Significance here was determined using a 2-tailed t test based upon 50 pooled samples with the multivariate imputation through the chained equations method. *P < 0.05; **P < 0.01; ***P < 0.001.
