In older attempters	No significant linear regression models were found.

Multivariate logistic linear regression analyses with the stepwise method were used in each group, and final models were presented.

Dependent variables were risk score, rescue score, and risk-rescue ratio score, respectively (log-transformed); independent variables were age (log-transformed), sex (male = 1 and female = 2), married (yes/no), alcohol intoxication (yes/no), interpersonal stress (yes/no), economic stress (yes/no), r/o schizophrenia (yes/no), and r/o bipolar disorder (yes/no).
