Fig. 2

Scatter plots and Violin plots of variables associated with drinking days. Each dot in each plot represents the data from one participant. The blue lines in the scatter plots show the fit of a linear model, and the gray area indicates the standard error. Dots on the plots of craving scores and gender have been jittered (0.1) to avoid overlapping dots. A scatter plot of years of education is not included due to resemblance with the age plot. ms = milliseconds
