Fig. 6: Correlation analysis between neuroimaging metrics and neural functional scores in patients with DCM after surgical intervention.

a The study revealed that the mJOA scores of DCM patients were positively correlated with the zALFF values in the PoCG.R. The 95% confidence interval ranges from 0.4668 to 0.7837. b–d The FC strength between the PoCG.R and several regions including PoCG.L, PreCG.R, and SMA.R was positively correlated with mJOA scores. The 95% confidence intervals for (b–d) are as follows: 0.02567 to 0.5187, 0.007765 to 0.5055, and 0.09874 to 0.5703. All P-values were corrected for multiple comparisons using the FDR method. The mJOA scores, zALFF and FC values represent the postoperative scores minus the preoperative scores.
