Multilevel Poisson regression predicting the number of previous suicide attempts at the time of new attempt with MDE status (fixed effects) and individual-specific liabilities (random effect).
| Effect type | Variable | β | RR | CI | p-value |
|---|---|---|---|---|---|
| Fixed | Intercept | 0.536 | 1.708 | 1.08–2.63 | 0.018 |
| Fixed | Partial remission | −0.191 | 0.826 | 0.58–1.18 | 0.283 |
| Fixed | Full MDE | 0.010 | 1.010 | 0.70–1.48 | 0.957 |
| ση | CI | ||||
| Random | Intercept | 1.060 | 0.85–1.33 |
β = regression coefficient, σ = random-effect (trait, or η in Equation 1) variance.
MDE, major depressive episode; RR, implied rate ratio/multiplier; CI, confidence interval of left-hand value.
