HH, High drinking/High symptoms; NM, No drinking/Moderate symptoms; LN, Low drinking/No symptoms; LH, Low drinking/High symptoms; LM, Low drinking/Moderate symptoms.

Entries are relative risk ratios (RRRs) with 95% confidence intervals.

The most severe group, HH, is the reference level. Bolded entries have P < 0.05.

Models were adjusted for all variables in the table.
