The analysis pipeline for our current study. In our current study, we calculated the grey matter volume (GMV) in all participants (both degenerative cervical myelopathy patients and healthy controls). We grouped the DCM patients into two subgroups based on postoperative numerical rating scale (NRS). Voxel-wise one-way ANOVA was performed, and post hoc analyses were performed. The mean GMV values within the resultant clusters were extracted and correlated with the clinical measurements in all patients, in PAP and nPAP. Finally, machine learning analyses were performed via support vector machine (SVM) for PAP vs. nPAP classification based on GMV alterations identified by ANOVA as features
