What is this? The presence of certain comorbidities, such as diabetes mellitus, may represent potential risk factors for poorer outcomes for patients with COVID-19.

In this rapid meta-analysis, the authors searched for case-control studies of the relationship between diabetes and COVID-19 mortality and severity and to determine the prevalence of diabetes in patients with COVID-19. They restricted their search to articles published in English since 1 January 2020 and did the search on 22 April 2020. They included 33 studies (total: 16,003 patients) from China (30 studies), France (1) and the USA (2).

What was found: At the time of this review, the included studies showed that approximately 10% of patients with COVID-19 had diabetes, and that diabetes was associated with a two-fold increase in mortality and severity for COVID-19 patients, compared to those without diabetes.
