Table S1 provides the mean (SD) total CTQ and subscale scores for the groups of participants who had and had not, attempted suicide. Fig. 2 shows that, irrespective of substance dependence and gender, suicidal behavior was associated with higher childhood trauma scores and that the proportion of women attempting suicide was numerically but not significantly greater compared with men in both the substance dependent group (0.40 vs 0.30, p = 0.265) and the non-substance dependent group (0.12 vs 0.06, p = 0.524).
