TMS parameters at baseline dependent on BDNF-genotype

	Met carriers	Val/Val carriers	p*
RMT (%)	39.9 ± 5	41.1 ± 8	0.54
Baseline MEP (μV)	775 ± 363	707.3 ± 209	0.68
Stimulation intensity (%)	49.8 ± 7	51.9 ± 9	0.42
Perceptual threshold (mA)	2.6 ± 0.9	3.3 ± 1.1	0.094

RMT and stimulation intensity to evoke a 0.5–1 mV MEP are given as percentage of maximum stimulator output. Data are given as mean ± SD. No significant group differences were found.

*Paired t test or Wilcoxon rank test, as appropriate.
