*Multiple comments: | |||
**"The study by Alzahrani et al. used data from the National Health Interview Survey, which contains no information about when participants started to smoke or vape, and when they were diagnosed with a myocardial infarction." (Rodu) | |||
**"E-cigarettes first appeared in the US at about 2009 and their use picked up from about 2013. In the cohorts from 2014 and 2016 that this study used, most participants with a history of MI can be expected to have had their MI before they tried e-cigarettes...The authors’ conclusions are thus misleading on an important public health issue. The article has been used e.g. to claim that vaping increases risk of cardiovascular disease by the WHO Director Ghebreyesus (DOI: 10.1016/S0140-6736(19)31730-1). The data that the paper reports show no such thing." (Hajek) | |||

**"Alzahrani and colleagues rightly point out that their models test for and thus demonstrate statistically independent effects of smoking and vaping, but if vaping and smoking are not actually independent contributors to identifying MI occurrence—that is, if the association between e-cigarette use and MI occurrence varies as a function of combustible cigarette use—then the main-effects model cannot be used to draw conclusions about the association between e-cigarette use and MI, independent of (or regardless of) one's history of combustible cigarette use." (Critcher, Siegel) | |||

**"As the debate on the risks−benefits of electronic-cigarettes continues, a rigorous evidence base is critical. Although determining whether the use of e-cigarettes carries excess risk for future MI is important, it is not possible through the analysis of cross-sectional data, such as the National Health Interview Survey data, from which temporality cannot be inferred. Equally important, we were unable to replicate the authors’ findings. Given the importance of this topic to public health, we request that the authors provide a full and comprehensive explanation for the discrepancies noted and temper their conclusions about “increased risk of myocardial infarction” to reflect the limitations of cross-sectional data." (Bover Manderski, Delnevo) | |||

**"Our findings show the well-established limitations of cross-sectional studies, which cannot justify any claims about causal inference, as mentioned in the conclusion by Alzahrani and colleagues.1 Therefore, the conclusion of their study is incorrect and should be revised."
