The second one says: "In other words, the association of moderate drinking and reduced mortality among older adults is reduced but still present when taking into consideration factors that affect both alcohol consumption and mortality," said Moore.

That is, those with higher income and/or education are less likely to be abstainers and to die."

This IS confusing. I think I'll have a few beers while I think about it.
