| Nair et al. [40] | Vitamin D: The “sunshine” vitamin | Supportive data for the effective role of VD in decreasing the risk of COVID-19 could be highlighted by increased case-fatality rates with chronic disease comorbidity and age, in which lower concentrations of 25(OH) D have been reported. |
| Epidemiology Working Group for NCIP Epidemic Response, Chinese Center for Disease Control and Prevention [41]. | The Epidemiological Characteristics of an Outbreak of 2019 Novel Coronavirus Diseases (COVID-19) in China | Since VD levels decrease with age, it may be important to assess the risk of VD as a factor owing to its high case fatality in older age groups. |

Treatment of Community Acquired Pneumonia (CAP) with VD did not significantly result in complete resolution but led to decreased concentration of IL-6, CRP in diabetic patients. VD contributes to the increased risk of ARDS development. |

1. Vitamin D deficiency is independently associated with mortality among critically ill patients. 2. Vitamin D deficiency in critically ill patients. |
There may be an etiological association between low VD levels, positive blood cultures, and mortality in critically ill patients admitted to ICU. |
