Note: Binary linear regression is based on paired data displayed in Supplemental Material Table S3. SES Socioeconomic status
a Suicidal behavior includes suicidal acts or attempts, presently at T2 or ever, also suicidal acts and attempts with suicidal thoughts
b RD is risk difference, the difference between the proportions of patients with suicidal thoughts or behavior and negative life events compared with patients with suicidal thoughts or behavior without negative life event
c The numbers in this table, for example 3/73 (4.1) and 63/462 (13.6), indicate that among the 73 patients with no negative life event, 3 had suicidal ideation at T2, and among the 462 patients with the negative life event, 63 had suicidal ideation at T2
d Estimates could not be computed due to non-convergence of the calculations
e The risk of having suicidal behavior decreases with 2.3% per one unit increase in level of mothers education
