^aN/A indicates that the article was not found in Google Scholar, Web of Science or Scopus, sometimes because the journal was not indexed
^bThe Wilcoxon matched-pairs signed-rank test was used to test the difference between the number of citations to each co-publication and its corresponding CEVG review in each database (Google Scholar, Web of Science, and Scopus, respectively). We considered a value of P < 0.05 to indicate a statistically significant difference in numbers of citations between a co-publication and its corresponding CEVG review
