Fig. 1

Meta-analysis of 14 studies of substance (alcohol)-related disorders and suicidal risk (a forest plot). The center of a box and the horizontal line (logarithm) indicate the odds ratio (OR) and the 95% confidence interval (CI) in each study, with the areas of the boxes representing the weight of each study. The summary OR based on random effects model is represented by the middle of a diamond whose width indicated the 95% CI. The summary OR is shown by the broken vertical line. Statistical heterogeneity between studies was assessed with Cochran’s Q test (Q = 69.05, P < 0.001). Summary OR = 5.24 (95% CI = 3.30–8.31)
