Positive sign in the peak t-score represents increase, and negative sign represents decrease. All P <0.05, corrected for multiple comparisons using AlphaSim program. ΔVol: volume difference; ALFF = amplitude of low frequency fluctuation; TIPS = Transjugular intrahepatic portosystemic shunt; BA = Brodmann's area; PCu = precuneus; MPFC = medial prefrontal cortex; ACC = anterior cingulate cortex; SMA = supplementary motor area; DLPFC = dorsal lateral prefrontal cortex.
