The editorial team at The Lancet Haematology would like to extend our thanks to the many experts who offered their time and expertise to help us make decisions on and improve papers in 2020. This is particularly the case in the year of the COVID-19 pandemic where health and medical services have been stretched to their limit and the whole world has needed to come to grips with a new way of working.
Today we publish as an appendix a list of clinical and statistical peer reviewers, we hope that some small recognition of an important academic task can be given to those who give their time, knowledge, and expertise.
We have been working to increase the diversity of our peer review pool. At the beginning of 2020 we made a commitment to working towards parity between male and female reviewers and have seen an improvement within our clinical reviewers from 30% women reviewers in 2019 to 40% in 2020, we hope to continue with our progress next year and beyond. We are also committed to listening to a more diverse global voice and continue to invite researchers from low-income and middle-income countries.
We look forward to continuing our work in 2021 to develop The Lancet Haematology into a leading journal for the haematology and haematology-oncology communities, with a clear focus on clinical care and research.
