AUDIT-C metrics were associated with PEth values (Figure 1). Median time between PEth and closest AUDIT-C was 2.3 years (IQR=1.7-2.8). All three AUDIT-C metrics (closest, highest, and trajectory) were associated with PEth values (median and PEth thresholds 8+, 20+ and 100+). This was true both when all race/ethnicities were included and when just AAs were included, all p <0.001 (Figures 1a and 1b). AUDIT-C trajectory demonstrated the steepest gradient, followed by closest AUDIT-C, with highest AUDIT-C showing the lowest gradient.
