After Bonferroni correction, we found a significant suicide risk associated with 6 variables: Parkinson's disease, depressive disorder, obsessive-compulsive disorder (inverted association), elevated serum aspartate aminotransferase levels, male gender and age. Before Bonferroni correction, variables such as cigarette smoking, heavy alcohol drinking, psychotic disorder, other psychiatric disorder, benzodiazepine use and higher fasting glucose showed some significant association. In addition, body mass index and height were inversely related to completed suicide before Bonferro...
