Why is this research important: A lot of studies have shown that light increase in alcohol consumption may protect from cardiovascular diseases and reduce chances of strokes and heart attacks. However, the data analysis in majority of those studies was biased, as most of them did not take into the account sick quitter phenomenon (non-drinkers in control group tend to be less healthy thank light drinkers, as they abstain from drinking due to health issues in a first place), other harmful effects of alcohol and inappropriate selection of reference group.

What did the researchers do: In this study, researches analysed data from 490,255 subjects. After thorough removal of uncompleted or biased entrances of data, researches compared the amount of drinking to all-cause mortality and the possibility of cardiovascular diseases.
