CON subjects were voluntarily enrolled in non-treatment NIAAA research protocols during the same period of time that the AD subjects were admitted as inpatients. While the CON subjects had no current or past alcohol dependence diagnoses, the sample did include some heavy drinkers (5 or more drinks in a day for males, and 4 or more drinks in a day for females) and several individuals (n = 10) who met criteria for current alcohol abuse. Table 1 provides subject sample characteristics for both AD and CON subjects.
