"Funding We gratefully acknowledge the 161,808 women who enrolled in the Women’s Health Initiative almost 30 years ago, and those who are able to remain active and engaged partners in this journey to advance our understanding of the health and well-being of women. We are particularly grateful to the 49,695 women who participated in the WHI COVID-19 Survey – 1, launched during a disruptive period in their lives. Their generosity adds critical information on the impact of the pandemic on one of our most vulnerable populations. We also thank the WHI Clinical Coordinating Center at Fred Hutchinson Cancer Research Center for conducting the COVID survey and providing financial and statistical support for this effort, as well as the four WHI Regional Centers who assisted in conducting the COVID-19 Survey - 1 (Stanford School of Medicine, The Ohio State University College of Medicine, University at Buffalo School of Public Health & Health Professions, and Wake Forest University Health Sciences). Finally, we thank Wake Forest University Health Sciences for providing the financial support for publication costs that made this supplement possible."
