Retrospective 50 COVID-19 hospitalized patients in Italy with vitamin D levels measured on admission, and 100 matched control patients, showing significantly lower vitamin D levels in COVID-19 patients. Vitamin D levels were also lower in COVID-19 patients with severe cases, without reaching statistical significance (p = 0.08, details not provided).
