CCK and alcohol drinking: Multivariate logistic regression analysis was subsequently performed, and the results were as follows: alcoholism (OR: 3.521, 95% CI: 1.061∼3.183), GAS (OR: 5.020, 95% CI: 0.218∼0.675), VIP (OR: 3.227, 95% CI: 1.072∼2.901), MTL (OR: 4.019, 95% CI: 1.467∼4.218), CCK (OR: 4.629, 95% CI: 1.353∼5.727), miR-155 (OR: 6.786, 95% CI: 8.824∼19.856), and miR-21 (OR: 2.664, 95% CI: 1.347∼8.783).
