Recognized Outstanding Reviewers for Circulation in 2021.

The quality and impact of the articles we publish in Circulation depend critically on the contributions and efforts of our extended team of peer reviewers, comprising hundreds of colleagues around the world. Although we received reliably outstanding reviews of all of the articles we submit for peer review, and we are grateful to every person who has contributed to Circulation in this way, a few reviewers have risen to the top, and we recognize them here. Please find our list of the Circulation Top Reviewers for 2021. This list is based on objective criteria of the quality of reviews provided, total number of papers reviewed, proportion of invitations accepted, and timeliness of review submissions. Many thanks and congratulations to all.
