English: "the sample was reduced to 847 512 references made by 193 802 Wikipedia articles to 598 746 scientific articles belonging to 14 149 journals indexed in Scopus."

"The mean publication date of the scientific papers cited is 2001; most were published between 1988 and 2018 (88.51%) as Fig 3 shows. Some 39.43% were published between 2008 and 2018. To analyze the literature on obsolescence, we used the Price index [27], which reflects the percentage of references within a given period. Our results indicate that 36.84% of citations appear within 5 years of publication, twice as many appear within 15 years, and 83.46% appear within 20 years (Fig 4)."

"As highlighted results we found a significative presence of “Medicine” and “Biochemistry, Genetics and Molecular Biology” papers and that the most important journals are multidisciplinary in nature, suggesting also that high-impact factor journals were more likely to be cited."
