Study Arms:
- Saline (Type: PLACEBO_COMPARATOR): Participants received intravenous saline immediately prior to sham and real rTMS of the left dorsolateral prefrontal cortex. The parameters of the stimulation paradigm are as follows: 10 Hz, 5 seconds on, 10 seconds off, 20 minutes, 4000 pulses).
- Naloxone (Type: ACTIVE_COMPARATOR): Participants received intravenous naloxone (0.1mg/kg) immediately prior to sham and real rTMS of the left dorsolateral prefrontal cortex. The parameters of the stimulation paradigm are as follows: 10 Hz, 5 seconds on, 10 seconds off, 20 minutes, 4000 pulses).

Based on this trial design, predict the completion outcome and termination type (if applicable).
