- wcoenen 5y agoIn the study they say that 27% of the variance is explained by age. So the effect of alcohol consumption certainly is insignificant compared to the effect of age. However, the authors think the effect of alcohol is notable because that 0.8% was still larger than any other factor they tested, like smoking.

Current ‘low risk’ drinking guidelines should be revisited to take account of brain effects. The authors are pretty clear. You are, of course, free to draw your own conclusions.
- brummm 5y agoNo, it was found to have a statistically significant influence on grey matter volume.
- Godel_unicode 5y agoStatistically significant just means that the results are correlated at greater than some probability, not that the effect itself is significant. I.E. you can have a statistically significant but unimportant effect.
