In an update of their article, they provide an answer to my previous comment by “clarifying” that their conclusion was that certain e-cigarettes may be more toxic that certain
tobacco cigarettes. This conclusion, as I have already mentioned in my previous analysis, can be made only if you select the best result from a
tobacco cigarette with the worst result from an electronic cigarette. However, they still fail to understand that this is incompatible with basic principles of science and research.
