Stimulation was performed using a figure 8-shaped focal coil attached to a MagPro 100 magnetic stimulator (MagVenture, Copenhagen, Denmark). All patients received 1 Hz (10 s trains, 1 s inter-train interval, 1,360 pulses per session) rTMS treatment once daily on weekdays for 2 consecutive weeks. rTMS was delivered over the right DLPFC (F4 electrode site according to the International 10-20 EEG system) at 100% of the resting motor threshold (RMT) . To determine the RMT, stimulus intensity was gradually increased until 5 out of 10 trials elicited motor evoked potentials with peak-to-peak amplitudes over 50 μV in the contralateral abductor pollicis brevis muscle. Adverse events attributed to rTMS were documented and reported. All participants received a pre-treatment assessment with the PSQI, HAMA, and HAMD. We used the PSQI to measure sleep quality, as well as HAMA and HAMD to assess participant's anxious and depressive states. Likewise, the PSQI was measured post-treatment (upon completion of the final treatment session) and at 1-month follow-up.
