All values are expressed as mean (standard deviation).

a

Degrees of freedom 2, 111.

b

Probability error for the one-way ANOVA omnibus test.

BD, bipolar disorder; FEM, first episode mania; HS, healthy subject; RMT, resting motor threshold (% of maximum machine output); MT1, motor threshold 1 (% of maximum machine output); SICI, % effective inhibition measured using short-interval intracortical inhibition; LICI, % effective inhibition measured using long-interval intracortical inhibition; LSD, least significant difference; SI1 mV, stimulation intensity to elicit a 1-mV motor evoked potential. The bold values indicate that the P values are statistically significant. (ie, P < 0.05).
