Impact of gender categories and scores on adverse event (AE) reporting. The probability of reporting any AE in each gender category was estimated using mixed effects logistic regression models to account for repeat measurements on participants over three influenza seasons (A). The model was then expanded to include an interaction term between sex and gender (B). Using similar models, the effect of femininity (C-D) and masculinity (E-F) scores on the probability of reporting any AE was estimated for the overall population (C & E) and separately for males and females (D & F). No p-values are shown because no comparisons were statistically significant
