Table 3: Summary statistics for Articles Topic and Study design, number (N) of articles per topic and study design, Altmetric Attention Score (Total), AAS per Item, and citation count in Web of Science (Total) Scopus (Total) are presented. Data are segregated per year (2019 and 2021). According to the data gathered in 2021, a total of 55 items presented an AAS decrease during the studied period, and in most of the cases (46) this was due to a decrease in the registered number of Tweets. A decrease was also noted for Mendeley readers in 241 published items.
