The influence of diabetes and hyperglycemia on short and long-term mortality after the first-ever known COVID-19 infection
Authors' conclusion
Diabetes associated with other comorbidities had the highest risks of all-cause mortality in the short and long-term, hyperglycemia was a long-term marker of poor prognostic after COVID-19 infection.
