Last but not least, results suggest that the patterns differ more by living arrangement during the second year of the lockdown: the fluctuation in alcohol consumption is very similar until November 2020 (although drinking levels differ). Yet, from November onwards those living alone show a slow but steady increase in the pattern, whereas those living with partner/family have a much greater variation in the slope. Consistently, as shown in Table 1, the interaction term for those who lived alone in May 2020 was β = 0.02 (CI95% −0.08 to 0.12), whereas in the same month in 2021 it was β = 0.22 (CI95% 0.10–0.35).
