Analysis of Asian countries finding that prevalence of vitamin D deficiency and lower vitamin D levels were associated with COVID-19 infection and mortality.
Positive correlations were observed for prevalence of vitamin D deficiency with COVID-19 infection (r = 0.76, p
= 0.002) and mortality (r = 0.65, p
= 0.03), after predicting with confounding factors. Mean vitamin D level had a significant negative correlation with COVID-19 infection (r = 0.77; p
= 0.04) and mortality (r = 0.80, p
= 0.03) when combining with confounders.
