Impedance, perceived intensity and side-effects
REGRESSION
There was no statistically significant main effect of stimulation type on impedance [In terms of overall side-effects of stimulation, there was a statistically significant main effect of stimulation type [Mixed effects ordinal logistic regression analyses found that participants were 16.2 and 8.1 times more likely to perceive stimulation as longer during tDCS and theta tACS compared to sham stimulation, respectively (
