Century old? Did they have enough data on non smokers at that time to draw any hard conclusions?

- bell-cot 1y agoEvidently "yes": https://upload.wikimedia.org/wikipedia/commons/9/94/Cancer_smoking_lung_cancer_correlation_from_NIH.svg https://upload.wikimedia.org/wikipedia/commons/9/94/Cancer_s...

- AlecSchueler 1y agoThat seems to tell us a lot about the correlation between smoking and lung cancer but I'm not sure how to read from it that there was enough data on non-smokers to talk with certainty about other environmental factors. My understanding is that after the push for women to start smoking around that time it would have been almost impossible to find study subjects who weren't at least exposed to high levels of second hand smoke.
