    Objective: We assessed studies probing at vitamin D deficiencies in both positive and negative COVID-19 cases. Methods: We measured mean, standard deviations, and 95% Confidence Interval (CI) of many studies to determine if there is a consistent relationship between vitamin D levels and COVID-19. Independent sample t-test compared non-survivors vs. survivors of COVID-19 and vitamin D levels, and moderate vs. severe COVID-19 symptoms and vitamin D levels. Results: We evaluated the difference in vitamin D levels (serum 25(OH)D, nmol/L) among those who tested positive for COVID-19 to those who tested negative. The average median serum 25(OH)D, nmol/L for patients who tested positive was 27.08 nmol/L (± 0.58 SD, 95% CI: 1.88) and the average median of serum 25(OH)D, nmol/L for patients who test.. Read More»
