Figure 7. Correlations between glutamate C4 and glutamine C4 enrichments and recent drinking history for both heavy drinkers and light drinkers.

Figure 7

(A) Correlation with drinks in the past 30 days for Glu4 (P = 0.0005) and Gln4 (P = 0.1). (B) Correlation with days of drinking in the past month for Glu4 (P = 0.098) and Gln4 (P = 0.03). Gray diamonds represent Gln4 13C enrichments, and white squares represent Glu4 13C enrichments.
