The reference groups for the odds ratios (ORs) were incorrectly reported. In the partial proportional odds models for ordinal dependent variables estimated in the manuscript, ORs should represent the likelihood of being in higher frequency or quantity categories compared to lower categories for each 10-hour increase in weekly work hours or $50 increase in weekly earnings. For example, the “1–4 drinks” OR represents the odds of being in the 1–4 or 5+ drinks per day categories (i.e., any drinking) compared to zero drinks per day. The “5+ drinks” OR represents the odds of being in the 5+ drinks per day category compared to the odds of being in the zero or 1–4 drinks per day categories. Importantly, our estimates were correct but interpreted incorrectly. However, our overall conclusions remain unchanged.
