Differences in baseline variables across categories of alcohol consumption were assessed using one-way ANOVA or Kruskal-Wallis test for continuous variables and χ² test for categorical variables. Alcohol consumption was categorised into low consumption (<30 g/week among women and <51 g/week among men), moderate consumption (30–65 g/week among women and 51–104 g/week among men) and high consumption (>65 g/week among women and >104 g/week among men).
ANOVA, analysis of variance; BMI, body mass index.
