Lastly, we compared those with AUD who reported a suicide attempt and those with AUD who did not report a suicide attempt across neurophysiological measures (resting state EEG coherence), again using multiple-group, multi-level regression models adjusted for sex, age (at time of psychiatric assessment), genetic similarity, family history of AUD, and family relatedness. We ran all models simultaneously to limit multiple testing.). We also performed a series of exploratory analyses within a subset of individuals who had available neurocognitive measures (see supplemental information for full description).
