Serum total ghrelin level was correlated with the increase in alcohol urge measured by the increase in the Alcohol-Visual Analogue Scale (dA-VAS) during both the first (p = .008; Figure 3A) and the second (p = .005; Figure 3B) alcohol cue trials. The maximum serum total ghrelin peak level across the six measurements was correlated with the increase in alcohol urge both in the first (p = .02; Figure 3C) and the second (p = .04; Figure 3D) alcohol cue trials.
