Retrospective 216 COVID-19 patients and 197 population controls, showing vitamin D deficiency in 82.2% of COVID-19 cases and 47.2% of population-based controls (P < .0001). Authors note: "We did not find any relationship between vitamin D concentrations or vitamin deficiency and the severity of the disease". While no association was found within hospitalized patients, there is an association with hospitalization, and hospitalization is an indication of COVID-19 severity.
19 of the COVID-19 patients were taking vitamin D supplements, showing lower ventilation and ICU admission, but no significant difference in mortality.
This is the 23rd of 175 COVID-19 sufficiency studies for vitamin D, which collectively show higher levels reduce risk with p<0.0000000001 (1 in 18 vigintillion).

Background: The role of vitamin D status in COVID-19 patients is a matter of debate. Objectives: To assess serum 25-hydroxyvitamin D (25OHD) levels in hospitalized patients with COVID-19 and to analyze the possible influence of vitamin D status on disease severity. Methods: Retrospective case-control study of 216 COVID-19 patients and 197 populationbased controls. Serum 25OHD levels were measured in both groups. The association of serum 25OHD levels with COVID-19 severity (admission to the intensive care unit, requirements for mechanical ventilation, or mortality) was also evaluated. Results: Of the 216 patients, 19 were on vitamin D supplements and were analyzed separately. In COVID-19 patients, mean ± standard deviation 25OHD levels were 13.8 ± 7.2 ng/mL, compared with 20.9 ± 7.4 ng/mL in controls (P < .0001). 25OHD values were lower in men than in women. Vitamin D deficiency was found in 82.2% of COVID-19 cases and 47.2% of population-based controls (P < .0001). 25OHD inversely correlates with serum ferritin (P = .013) and D-dimer levels (P = .027). Vitamin D-deficient COVID-19 patients had a greater prevalence of hypertension and cardiovascular diseases, raised
