Retrospective 93 hospitalized patients with vitamin D levels 1-365 days before admission, not showing significant differences with vitamin D deficiency or vitamin D levels. Vitamin D levels may vary significantly throughout the year creating a major cofounder that authors do not adjust for.
This is the 34th of 209 COVID-19 sufficiency studies for vitamin D, which collectively show higher levels reduce risk with p<0.0000000001 (1 in 293,154,636 vigintillion).
risk of death, 5.6% higher, RR 1.06, p = 1.00, high D levels 14 of 58 (24.1%), low D levels 8 of 35 (22.9%).
risk of mechanical ventilation, 39.7% lower, RR 0.60, p = 0.21, high D levels 10 of 58 (17.2%), low D levels 10 of 35 (28.6%), NNT 8.8.
risk of no hospital discharge, 26.7% higher, RR 1.27, p = 0.50, high D levels 21 of 58 (36.2%), low D levels 10 of 35 (28.6%).

Context: Populations severely affected by COVID-19 are also at risk for vitamin D deficiency. Common risk factors include older age, chronic illness, obesity, and non-Caucasian race. Vitamin D deficiency has been associated with risk for respiratory infections and failure, susceptibility and response to therapy for enveloped virus infection, and immune-mediated inflammatory reaction. Objective: To test the hypothesis that 25-hydroxyvitamin D[25(OH)D] deficiency is a risk factor for severity of COVID-19 respiratory and inflammatory complications. Design: We examined the relationship between prehospitalization 25(OH)D levels (obtained 1-365 days prior to admission) and COVID-19 clinical outcomes in 700 COVID-19 positive hospitalized patients.
