  1. The sample sizes of individuals with available information on the subphenotypes were listed as “N available”. Statistics are percentages for categorical variables (N of subphenotypes divided by N available) and mean ± SD for continuous variables. Statistical comparisons are t test for continuous variables and chi-square test for categorical variables. All statistical comparisons exceed Bonferroni correction (N = 7, P < 0.007).
  2. SD standard deviation, BD1 bipolar disorder subtype 1, BD2 bipolar disorder subtype 2, BD NOS bipolar disorder not otherwise specified, GAF-function global assessment of functioning, function dimension, GAF-symptom global assessment of functioning, symptom dimension, NA not applicable.
