Data for: Hungry to gamble? Ghrelin as a predictor of persistent gambling in the face of loss

This data set was obtained from a study looking at the association between plasma ghrelin and gambling behaviour. Subjects were either fasted or not, and later were brought to a lab with either gambling or no gambling cues. Our data suggest that the cues increase ghrelin, and that, overall, regardless of the manipulation, ghrelin concentrations can predict gambling perseverance.
