Analysis of covariance (ANCOVA) conducted with years of education as a covariate. BD = Bipolar Disorder, hBPM = human Behavioral Pattern Monitor, HCS = healthy comparison subjects, M = estimated marginal mean, SE = standard error.
a
Acceleration measured in digital units (estimated marginal mean, standard error).
b
Epochs 1-3 = 1-15 min.
c
Epoch 1 = 1-5 min.
d
Epoch 2 = 5-10 min.
e
Epoch 3 = 10-15 min.
