Concept map displaying 10 clusters ECIG user-identified statements describing the impacts of COVID-19 on vaping. Numbered points on the map that are closer to one another represent statements of more similar content whereas points on the map that are further apart represent statements of less similar content. Greater number of layers in clusters indicate higher mean ratings of statements within each cluster based on the rating task. Mean ratings for clusters with 1 layer range from 2.84 to 3.10, 2 layers from 3.10 to 3.36, 3 layers from 3.36 to 3.61, 4 layers from 3.61 to 3.87, and 5 layers from 3.87 to 4.13.
