My comment is not nonsense insofar as this study is going to be ignored but the statistically manipulated “study” about second hand smoke is considered gospel and has actually put people out of work and out of business.
It is all about political correctness and has nothing to do with the legitimacy of the study.
For statistical significance an increased increased risk (a/k/a relative risk) needs to be over 200% and preferably over 300%.
There is no relationship between your numbers of 200% and 300% and the concept of "statistical significance" which has a specific technical meaning.
