Note. This column shows the percentage of probands who met criteria for a mood disorder, broken down by whether or not the proband had at least one parent, a mother, or a father with a mood disorder history themselves. The first number in the ratio in parentheses is the number of probands positive for a mood disorder in that category; the second number in the ratio is the total number of families in that category (e.g. 4/9 means that of the 9 families with a positive family history of mood disorder in at least one parent, 4 of those families had a proband with a mood disorder).
