There is an error in the last sentence of the Primary outcome subsection of the Results. The correct sentence is: The median number of units consumed a week in both intervention and control groups at follow-up was within recommended weekly limits (≤14 units per week for women; ≤21 units per week for men), with the exception of women in the intervention group (Table 2).
