Harm
- What it counts
- Total, serious adverse events
- Time frame
Adverse events were monitored from the start of assigned treatments (1 mA and sham) through study completion. This involved collection of information about adverse effects daily at the beginning and end of each treatment session and then again at the 3-month follow-up visit.
