Our prior report (King et al., 2014(34)) indicated that the HD and LD continued to differ significantly through follow-up on all measures of alcohol drinking behaviors and problems. Table 1 depicts demographic, health, and drinking comparisons between the groups, and Supplemental Table S1 depicts baseline characteristics of the groups. In brief, the LD largely continued with low-risk drinking. While they consumed alcohol more frequently over time, binge drinking and alcohol problems were rare, and they formed one low-risk trajectory group(34). In contrast, the HD comprised three AUD subgroups over time, derived by trajectory analysis which differentiated those with low, intermediate, and high symptoms (see Table 1).
