a We assessed two functional indicators, zALFF and FC, alongside the structural indicator of GMV. b, c The FC strength between PoCG.R and both PoCG.L and PreCG.R was positively correlated with the zALFF value of PoCG.R. The 95% confidence intervals for (b, c) are as follows: 0.01797 to 0.5131 and 0.1032 to 0.5733. d The FC strength between PoCG.R and THA.L was negatively correlated with zALFF value of PoCG.R. The 95% confidence interval ranges from −0.5300 to −0.04120. All P-values were corrected for multiple comparisons using the FDR method. The zALFF and FC values represent the postoperative scores minus the preoperative scores.
