The hospital knowledge of 235 sufferers with COVID-19 had been analyzed.

 

In sufferers older than age 40, those that had satisfactory ranges of vitamin D had been 51.5% much less prone to have adversarial outcomes, together with changing into unconscious, hypoxia, and loss of life, as in comparison with vitamin D-deficient sufferers.
