Spearman’s rho correlation coefficients for the relationship of verbal fluency performance with stimulation at different contacts to patient-specific modeling indices.

Category fluency standardized residual change | ||||
Dorsal (N=14) | 0.37 | −0.42 | −0.34 | 0.36 |
Optimal (N=16) | 0.42 | −0.09 | 0.27 | 0.35 |

Indicates significance at the p<0.05 level.
Note. Negative change values indicate lower than predicted scores obtained with stimulation relative to OFF stimulation, and positive values indicate higher than predicted scores.
