BP-euth-D euthymic patients with a predominant depressive polarity, BP-euth-M euthymic patients with a predominant manic polarity
aFor two patients of the BP-euth-D group the information about the number of weeks in remission was not available
bOne patient of the BP-euth-D and four patients of the BP-euth-M had rapid cycling or a mixed episode as last experienced episode
