3.It has been suggested the moderate alcohol consumption is "protective" against cardiovascular disease (including stroke), and that a "J" shaped relationship exists. This implies that those with moderate alcohol consumption have the lowest risk, those with none/low consumption have intermediate risk, and those with high alcohol consumption have the highest risk. From your calculations in #1 and #2, do the data support the hypothesis of a "J" shaped relationship between alcohol consumption and risk of ischemic stroke?
a)Yes
b)No
c)Cannot be determined from the data provided
