Abbreviations: MRgFUS, magnetic resonance-guided focused ultrasound; N, number of patients in the group; n, number of events reported.
a
Represents the number of events experienced; more than one adverse effect may have been experienced by an individual patient. More than two complications in a single patient were counted as one.
b
Considered to be a modifiable side effect, which was resolved by adjusting the stimulation settings.
