  1. *Stable normal weekly alcohol consumption, reference group, with -0.49 to 0.49 SD = - 43.99 to 43.99 grams of 100% alcohol per week from T0 to T2.
  2. **Decreased normal weekly alcohol consumption with 0.5 SD = < - 44 grams of 100% alcohol per week or more from T0 to T2.
  3. ***Increased normal weekly alcohol consumption with > 0.5 SD = > 44 grams of 100% alcohol per week or more from T0 to T2.
  4. A: Crude OR for each separate variable.
  5. B: OR for each variable, adjusted for all variables in the model.
