Information Extraction and Synthesis
Included articles (n = 28) were dissected by the principal writer utilizing an information extraction table. The articles included have utilized a specific order of e-cigarette flavors for information decrease, either to clarify which flavors they vape juice utilized (eg, for trial arrangements) or to sort their outcomes (eg, for reviews). For example, Tackett et al.6 led a study in which e-cigarette flavors were spoken to by six classes: fruity, pastry kitchen/dessert, tobacco mixes, mint/menthol, candy/nuts, and espresso. From each article, the flavor classes utilized in the examination configuration were extricated. A qualification was made between principle flavor classes (eg, natural product or zest) and subcategories (explicit e-fluid flavors that speak to these classifications, eg, lemon or cinnamon). For example, the appropriate response alternatives of overview inquiries regarding purchasers’ favored e-fluid flavor (eg, “natural product” or “candy”) were fundamental flavor classifications, while the models that specialists used to clarify or determine these classifications (eg, “e.g., cherry, watermelon, kiwi” or “e.g., bubble gum”) were viewed as explicit e-fluid flavors that speak to the primary flavor classifications. Another model: if scientists contrasted sweet flavors and nonsweet flavors, we considered “sweet” and “non-sweet” as the principle flavor classifications. The models that scientists use as detail of these principle classes were considered subcategories (eg, “chocolate” or “vanilla” as subcategory of sweet flavors, and “tobacco” or “menthol” as subcategory of nonsweet flavors).
A portion of the primary flavor classifications or subcategories recognized from writing were utilized in more than one article; subsequently, commonness of each flavor class was resolved. Results were summed up in Table 1 that shows every primary flavor classification and related subcategories, (ie, flavor instances of the fundamental classes), which were utilized in the articles audited.
