TMS Protocols and Outcomes for STB

Protocol Type	STB Outcomes	Response Rate	Treatment Duration
Accelerated (aTMS/TBS)	Demonstrated significant and rapid decreases to suicidality	Up to 100% response	1–2 weeks
cTBS	Found to be superior to iTBS in one study for suicidality	72.73% remission	1 week (a-cTBS)
iTBS*	Found to demonstrate significant decrease in suicidality in multiple studies	65.63 – 93.33% response	1–2 weeks, (some a-iTBS)
dTMS	Found to demonstrate significant decrease in suicidality	41.2 – 70.6% response	4–6 weeks
rTMS (bilateral)	Found to be superior to sham in one study, specifically for bilateral treatment	40.4% remission	3–6 weeks
HFR rTMS *	Found to demonstrate significant decrease in suicidality in multiple studies	64.9% - 97.5% response	2–6 weeks
LFR rTMS	Found to have mixed-results and less efficacy than HFR rTMS	55.6%	2–4 weeks

Note:

^*High Frequency rTMS targeting the left dlPFC, and iTBS protocols were found to be the most consistent and effective protocols in reducing suicidality across the included studies.
