Notes: Canada’s Low-Risk Drinking Guidelines recommend no more than 2 standard drinks (SDs) for women/3 for men (daily) and no more than 10 for women/15 for men (weekly). There were 5 participants in Analysis A, 16 in Analysis B, and 10 in Analyses C and D who answered “prefer not to say” or no response and who were excluded from the analyses. The correct SD category ranges were as follows: 1.26–1.54 standard drinks for beers, 4–6 for wine, 16–20 for distilled spirits, and 0.9–1.1 for ciders. Values 10% above and below the accurate number of SDs for wine were used as the “correct” category. Bold indicates statistical significance.
