From: Leptin levels are reduced by intravenous ghrelin administration and correlated with cue-induced alcohol craving

Figure 3

Relationship between serum leptin levels expressed as leptin/BMI ratio after intravenous (i.v.) infusion of exogenous ghrelin (light blue) vs placebo (dark blue) and urge to drink alcohol or juice, measured by the Alcohol Visual Analogue Scale (A-VAS) and the Juice Visual Analogue Scale (J-VAS), respectively. (a) Leptin changes were significantly and negatively correlated with the increase in alcohol urge (r40=−0.342, P=0.031) during the alcohol trial (+29 min), (b) but not during the juice trial (P=NS). BMI, body mass index; NS, not significant.
