This is so skewed. 1800 participants, all with different health backgrounds, then divided into 3 groups of heavy, moderate and never. That's not really a sample

This is so skewed. 1800 participants, all with different health backgrounds, then divided into 3 groups of heavy, moderate and never. That's not really a sample size to get any definite conclusion from. These results might be a reason to do a more trough research at the most.
The variance on this thing is huge. To tie their drinking habits to their mortality, negating all other factors, on this sample size, is ridiculous.
- Retric 16y agoA sample size of 1800 / 3 where 40+% of them died is actually a fairly good for this type of research. The only real value for a larger sample size is the ability to measure smaller effects. And if the change is tiny then it's not really significant anyway.
