*Dr Farsalinos: “Increasing the risk” means that someone is FIRST exposed to a condition (in this case, exposed to e-cigarette use) and THEN, BECAUSE OF THIS EXPOSURE, he/she develops disease. Both studies CANNOT provide any of this information to substantiate an increased risk. Both are cross-sectional surveys, meaning that they asked participants if they have heart disease and if they use e-cigarettes. The studies provide no information on whether e-cigarette use was initiated before (and how long before) or after the development of disease. What if participants used e-cigarettes after they developed the disease in order to quit smoking? | *Dr Farsalinos: “Increasing the risk” means that someone is FIRST exposed to a condition (in this case, exposed to e-cigarette use) and THEN, BECAUSE OF THIS EXPOSURE, he/she develops disease.
