Retrospective 148 patients in Austria, showing no statistically significant differences in vitamin D levels and metabolites for mortality or respiratory support.
This is the 75th of 175 COVID-19 sufficiency studies for vitamin D, which collectively show higher levels reduce risk with p<0.0000000001 (1 in 18 vigintillion).
risk of death, 46.4% lower, RR 0.54, p = 0.08, high D levels 24 of 121 (19.8%), low D levels 10 of 27 (37.0%), NNT 5.8, >30nmol/L.
