Figure 4.
The baseline HDRS scores were negatively correlated with the slow 5 fALFF in bilateral SFGmed and bilateral ACC (cluster A) (r = −0.549, p = 0.000) at baseline. Decrease in HDRS scores (baseline HDRS scores minus follow-up HDRS scores) was positively correlated with the increased values in slow 5 fALFF (follow-up minus baseline) in bilateral SFGmed, bilateral SFG, bilateral ACC, and right MFG (cluster D) (r = 0.782, p = 0.000) and bilateral PCu, bilateral PCC, and left cuneus (cluster E) (r = 0.606, p = 0.002) at follow-up.
