So I'm looking at Figure 2 of the study and it shows that risk is negative (I.e. it's a benefit) below 7 drinks per week or 1 drink per day. And then they say "There was no protective net effect of alcohol observed at any level of alcohol consumption." And then they discuss the observed protective effects and just say "this body of evidence [that we used] has substantial limitations". They also say "Readers should therefore consider both the point estimates and their associated CIs when interpreting the risk thresholds presented in this study." but then their CI indicates only 2+ drinks per day can cause statistically significant issues.

Overall, a very boring study. It would be more interesting if they published the code and we could play with the numbers, seeing as all the data they used is public, but we can't even do that.
