Persistent negative symptoms at 1-year follow-up: logistic regression model
| Predictor | −2 log-likelihood | Nagelkerke R2 | χ2 | OR (95% CI) | p value |
|---|---|---|---|---|---|
| Step 1 | 44.09 | 0.27 | χ21 = 8.71 | 0.06 | |
| BDNF at baseline | 0.96 (0.93 to 0.99) | 0.018 | |||
| Step 2 | 33.16 | 0.53 | χ22 = 19.62 | ||
| Left amygdala relative volume | 0.99 (0.98 to 0.99) | 0.010 | |||
| BDNF at baseline | 0.93 (0.88 to 0.98) | 0.012 |
BDNF = brain-derived neurotrophic factor; CI = confidence interval; OR = odds ratio.
