CRP and chronic obstructive pulmonary disease: The ordinal regression analysis, taking the severity of the COVID-19 disease as the dependent variable, showed that higher temperature (ORa = 6.52), lower saturation (ORa = 0.88), higher BMI (ORa = 1.12), higher CRP (ORa = 1.01), being a female (ORa = 4.59), having diabetes (ORa = 8.11) and COPD (ORa = 10.03) were significantly associated with the increase on the COVID-19 severity.
