ALFF analysis
The data was processed by the Data Processing Assistant for rs‐fMRI (Restplus) based on Statistical Parametric Mapping 12 (SPM 12, The blood oxygen level‐dependent time series for each voxel was converted to the frequency domain with fast Fourier transform. The square root of the power spectrum was computed and averaged across the specified frequency range (0.01–0.08 Hz) at each voxel. The averaged square root was used as the ALFF, which was transformed by Fisher's To investigate the alternations in HCs and patients in POD 3, we used false discovery rates (FDR) correction for multiple comparison (voxel‐
