Discrepancies among Scopus and Web of Science, coverage of funding information in medical journal articles: a follow-up study

Abstract

Objective: This follow-up study aims to determine if and how the coverage of funding information in Web of Science Core Collection (WoS) and Scopus changed from 2015 to 2021. Methods: The number of all funded articles published in 2021 was identified in WoS and Scopus bibliographic databases using bibliometric analysis on a sample of 52 prestigious medical journals. Results: The analysis of the number of funded articles with funding information showed statistically significant differences between Scopus and WoS due to substantial differences in the number of funded articles between some single journals. Conclusion: Due to significant differences in the number of funded articles indexed in WoS and Scopus, which might be attributed to the different protocols for handling funding data in WoS and Scopus, we would still advise using both databases to obtain and analyze funding information.
