For the COVID-19 patients, we evaluated whether outcomes correlated with the following: clinical characteristics, diabetes type, prescribed diabetic medications, use of beta blockers, angiotensin converting enzyme inhibitors (ACE), angiotensin receptor blockers (ARB), severity of COVID-19 at admission as reflected by inflammatory marker C-reactive protein (CRP), and the initial oxygen saturation. The gene discussed is CRP; the disease is COVID-19.
