Fig. 3: The correlations analyses between a change of FC strength and a change of HAMD and MMSE in MDD in the main cohort of USTC.

a The increased FC strength of the left precuneus with the right lingual gyrus was negatively correlated to the changes of HAMD in MDD; b The increased FC strength of the left precuneus with the right precuneus was negatively correlated to the changes of MMSE in MDD; c The increased FC strength of the left precuneus with the left superior Parietal lobes was negatively correlated to the changes of MMSE in MDD; d The increased FC strength of the left angular with the left precuneus was negatively correlated to the changes of MMSE in MDD. lp left precuneus, rp right precuneus, lsp left superior parietal lobes, la left angular.
