“…In our study, the most frequently used keywords were “human/s”, “pandemic/s”, “COVID-19”, “female”, “Coronavirus Disease 2019”, “adult”, “anxiety”, and “male”. Apart from the keyword “human/s”, this study discovered that the research subjects in these types of studies were female, male, and adult, as they were in other bibliometric studies related to COVID-19 [ 65 , 66 ]. The other words, such as “pandemic/s”, “COVID-19”, “Coronavirus Disease 2019”, or “anxiety” indicated the dominance of keywords related to this theme, which is consistent with the results of other bibliometric studies about the COVID-19 pandemic [ 38 , 67 , 68 ].…”
