The first study on vitamin D and COVID-19 was released as a preprint on April 23, and a second study was released as a preprint on April 26. Here’s what we can learn from the second study. The first study, which I reported on a few days ago, focused on disease severity, while the second one, which I’m reporting on here, focused on mortality.
The Results
The electronic health records of 780 laboratory-confirmed COVID-19 cases from the government hospitals of Indonesia between March 2 and April 24 was searched for data on vitamin D status prior to admission, age, sex, preexisting conditions, and mortality. Vitamin D status was classified as normal (≥30 ng/mL), insufficient (21−29 ng/mL), or deficient (≤20 ng/mL).
