Retrospective 235 hospitalized patients showing a significant association between vitamin D sufficiency and reduction in clinical severity.
For patients over 40, mortality was 9.7% with 25(OH)D levels >30ng/mL, versus 20% for <30ng/mL.
A significant reduction in serum CRP, an inflammatory marker, along with increased lymphocytes percentage suggest that vitamin D sufficiency may help modulate the immune response possibly by reducing the risk for cytokine storm in response to this viral infection.
risk of death, 51.7% lower, RR 0.48, p = 0.08, high D levels 7 of 72 (9.7%), low D levels 27 of 134 (20.1%), NNT 9.6, age >40.
risk of mechanical ventilation, 31.6% lower, RR 0.68, p = 0.49, high D levels 6 of 77 (7.8%), low D levels 18 of 158 (11.4%), NNT 28.
risk of ICU admission, 32.0% lower, RR 0.68, p = 0.33, high D levels 11 of 77 (14.3%), low D levels 33 of 158 (20.9%), NNT 15, >30nmol/L.

The hospital data of 235 patients infected with COVID-19 were analyzed. Data Availability Statement: The data is part of the inpatient database of Sina Hospital COVID-19 Registry (SHCo-19R) and was used under license for the current study. The datasets used and analyzed during the current study will be available from the Research Development Center of Sina Hospital (Dr. Hale Ashraf; sina.research. development.center@gmail.com) on reasonable request. Based on the ethics board of Tehran University of Medical Sciences, access to data Results Based on CDC criteria, among our study patients, 74% had severe COVID-19 infection and 32.8% were vitamin D sufficient. After adjusting for confounding factors, there was a significant association between vitamin D sufficiency and reduction in clinical severity, inpatient mortality serum levels of C-reactive protein (CRP) and an increase in lymphocyte percentage. Only 9.7% of patients older than 40 years who were vitamin D sufficient succumbed to the infection compared to 20% who had a circulating level of 25(OH)D< 30 ng/ml. The significant reduction in serum CRP, an inflammatory marker, along with increased..
