Overview over all VBM analyses.

Research question	Statistics
	𝑛=41; (3 scans)	𝑛=36; (2 scans)	𝑛=77; (whole group 2 scans)
(1) Grey matter changes after rTMS?	Flexible factorial models with factors subject + time
	Time points: baseline, day 12, day 90	Time points: baseline, day 12	Time points: baseline, day 12
(2) Correlation between grey matter changes and clinical outcome parameters?	Correlation of difference in the TQ/loudness rating with difference images
	Time difference: day 12–baseline; day 90–baseline	Time difference: day 12–baseline	Time difference: day 12–baseline
(3) Grey matter as predictor for treatment response?	Correlation of difference in the TQ with baseline images
