Table 4. Logistic regression analysis for evaluating the risk factors for mortality in all patients with COVID-19 hospitalized in BSUH, United Kingdom.

P<0.05 was considered significant.

*Used for multivariate analysis, **compared to ≤60 years of age, ***include diabetes, asthma, COPD, heart disease, hypertension and cancer, ^HbA1c > 8.5%, ^^compared to type 1 diabetes, +diabetes excluded from risk factor (included Asthma, COPD, heart disease, hypertension and cancer), COPD: chronic obstructive pulmonary disease, BAME: Black Asian Minority Ethnicity, eGFR: estimated glomerular filtration rate, ND: not done.
