Conceptual structure evaluation working with MCA (Figure 3) showed that most reports on ENDS and HTPs are grouped into 3 categories: in vitro evaluation, which incorporates terms like cell-line and epithelial cells; animal models, which includes terms for example mice and lung; and human research, such as males, females, and young adults. We make use of these categories to group the findings within the revised articles.Int. J. FP Agonist manufacturer Environ. Res. Public Wellness 2021, 18,Int. J. Environ. Res.

We grouped the key phrases into three clusters and ran the MCA analysis with 20 words across all articles out there to search for relationships in more than 80 of your literature reviewed (Figure two). The conceptual structure analysis utilizing MCA (Figure 3) showed that most reports on ENDS and HTPs are grouped into three categories: in vitro evaluation, which incorporates terms for instance cell-line and epithelial cells; animal models, which contains terms such as mice and lung; and human studies, which includes males, females, and young adults. We utilize these categories to group the findings in the revised articles.Figure 2.
