Multivariate linear regression analysis to predict relapse severity (n = 35).
| Variables | R2a | S.E. | t | β (95% CI)b |
|---|---|---|---|---|
| Education years | 0.43 | 0.45 | −4.04 | −1.84 (−2.34, −0.59)** |
| mPFC_frontal superior_R | 8.07 | −4.32 | −34.84 (−51.44, −19.16)*** |
a
R2: adjusted R2 of determination coefficient;
b
β (95% CI): regression coefficient (95% confidence interval) which was based on the multivariate linear regression (stepwise) using relapse severity (AUDIT score at follow-up) as the dependent variable, and age, education years, AUDIT scores at baseline survey and changes FC as independent variables; NAc, nucleus accumbens; mPFC, medial prefrontal cortex; L, left; R, right;
**
P < 0.01;
***
P < 0.001.
