Note. Results reported as estimated marginal means, adjusting for Year 1 GHQ score, sex, race, ethnicity, neighborhood income, alcohol trajectory group membership, tobacco trajectory group membership, and baseline alcohol quantity. Groups sharing a superscripted letter within a given column are not significantly different (p>.05).
