  1. Since COVID-19 papers first appeared in JCR 2021, which covered publications from 2019–2020, the number of highly-cited non-COVID-19 papers is not shown for JCR 2018–2020 which covered publications from 2016–2019. Bold values highlight the extent of the decline in the number of highly cited papers after the removal of COVID-19 papers.
