Changes in tinnitus score and in multiple correlation coefficient during active and sham rTMS. a) mean reduction in tinnitus scores(ΔTQ) after active and sham rTMS is demonstrated. Error bars represent standard errors. b) multiple correlation coefficient between changes of excitability (ΔE) and changes in tinnitus score (ΔTQ) after active and sham stimulation. Clinical effect (ΔTQ) and correlation of ΔTQ and ΔE were strongest on day 11 (i.e. 6 days post intervention).
