Of the 96 alcoholic participants, 86 had Caine criteria scores (Table 3): 21 ALC participants did not meet any of the Caine criterion (Caine 0), 39 met 1 criterion (Caine 1), 24 met 2 criteria (Caine 2), 2 met 3 criteria (Caine 3), and no one met all 4 criteria. Given this distribution, Caine groups 2 and 3 were combined and categorized as the Caine 2+ group. Groups differed on age, total alcohol consumption, and DRS score, with Caine 1 younger than Caine 0 and Caine 2+, Caine 2+ having a higher lifetime alcohol consumption than Caine 1, and Caine 2+ scoring lower on the DRS than Caine 0 or Caine 1.
