Figures & data
Table 1. Frequency of key variables stratified by sex and drug use disorder (DUD) and post-traumatic stress disorder (PTSD) status.
Table 2. Adjusted hazard ratios for Cox models testing the self-medication and susceptibility models adjusted for covariates.
Table 3. Descriptive table for the cross-lagged panel model.
Figure 1. (a) Cross-lagged panel model of registrations of post-traumatic stress disorder (PTSD) and drug use disorder (DUD), starting at the age of 15 years, in 5 year epochs between the ages of 35 and 50 years. Five types of paths are shown: the ‘a’ paths refer to the stability paths for PTSD, the ‘b’ paths refer to the stability paths for DUD, the ‘c’ paths denote the within-time correlations between PTSD and DUD, the ‘d’ paths represent the self-medication pathway, and the ‘e’ paths denote the susceptibility pathway. (b) Standardized path coefficient results from the cross-lagged panel model, by sex.
