Retrospective 91 hospitalized patients, 36 treated with high-dose cholecalciferol, showing lower combined death/ICU admission with treatment.
Authors also analyze the relationship with comorbidity burden, finding that the positive effect of high-dose cholecalciferol on the combined endpoint was significantly amplified with increasing comorbidity burden.
risk of death/ICU, 36.6% lower, RR 0.63, p = 0.13, treatment 14 of 36 (38.9%), control 29 of 55 (52.7%), NNT 7.2, odds ratio converted to relative risk.

Abstract: Little information is available on the beneficial effects of cholecalciferol treatment in comorbid patients hospitalized for COVID-19. The aim of this study was to retrospectively examine
the clinical outcome of patients receiving in-hospital high-dose bolus cholecalciferol. Patients with a
positive diagnosis of SARS-CoV-2 and overt COVID-19, hospitalized from 15 March to 20 April 2020,
were considered. Based on clinical characteristics, they were supplemented (or not) with 400,000..
