An illustration of the dataset used in this study is provided in Fig. 1. DNA was available for a total of 830 participants: 141 suicide attempters and 689 non-suicide attempters. For G × E analyses, both DNA and CTQ scores were available for a total of 474 individuals, including 112 suicide attempters and 362 non-suicide attempters.
