The results are displayed in Table 3. The first three columns contain estimates of RRRs of predispositions, exp(βj1), for j = 1, 2, and 3 (β4 = 0, the fourth column). The fifth column gives the ratio of the estimates in column 1 (PTSD following sexual assault) and column 3 (PTSD following comparison trauma), i.e. exp(β11)/exp(β31) and its 95% confidence interval; the p value is in the sixth column. The last two columns together address the research question.
