  1. Note: Binary linear regression is based on paired data displayed in Supplemental Material Table S3. SES Socioeconomic status
  2. a Suicidal behavior includes suicidal acts or attempts, presently at T2 or ever, also suicidal acts and attempts with suicidal thoughts
  3. 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
  4. 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
  5. d Estimates could not be computed due to non-convergence of the calculations
  6. e The risk of having suicidal behavior decreases with 2.3% per one unit increase in level of mothers education
