Retrospective 15,968 hospitalized patients in Spain showing a significant reduction in mortality associated with the prescription of vitamin D, especially calcifediol, within 15-30 days prior to hospitalization.
risk of death, 33.0% lower, HR 0.67, p = 0.009, treatment 374, control 374, calcifediol, <15 days before hospitalization, Cox model with inverse propensity weighting.
risk of death, 27.0% lower, HR 0.73, p = 0.02, treatment 439, control 439, calcifediol, <30 days before hospitalization, Cox model with inverse propensity weighting.
risk of death, 25.0% lower, HR 0.75, p = 0.005, treatment 570, control 570, cholecalciferol, <15 days before hospitalization, Cox model with inverse propensity weighting.
risk of death, 12.0% lower, HR 0.88, p = 0.11, treatment 802, control 802, cholecalciferol, <30 days before hospitalization, Cox model with inverse propensity weighting.
