Pulmonary illnesses other than those associated with COVID-19 were not common: five patients (12%) had chronic obstructive pulmonary disease\u00a0(COPD), two (5%) had asthma. Nine patients (21%) were obese (BMI\u2009\u2265\u200930\u00a0kg\/m2<\/sup>).<\/li>\n

- There were no statistically significant differences between the groups in markers of inflammation or respiration.<\/li>\n
- After 10 days, patients with severe vitamin D deficiency had a 50% probability of dying, while those with vitamin D\u2009\u2265\u200910 ng\/mL had a 5% mortality risk.<\/li>\n
- Advanced age and elevated levels of inflammatory markers and poor respiratory function were also increased mortality.<\/li>\n<\/ul>\n
