31 total subjects, only 13 vitamin D deficient initially, p = 0.03. This study at best suggests further, more rigorous research here may be warranted. It says nothing about causation, for all that its authors seem to feel otherwise - and that they feel otherwise suggests its results should be taken with more than the usual amount of skepticism.

Have a look at table 1. Only 5/31 subjects had “sufficient” vitamin d. In between deficient and sufficient there is the insufficient category, from 20-30 ng/ml.
Though I agree further study is warranted. The highest vitamin D group actually had the highest mortality after 84 days. Though this group also had the most pre-existing heart conditions by far, so that could account for it.
Ah, there was a second such study in the pdf. Mortality down by almost half.
——————
Intervention was carried out intramuscularly with 300,000 IU of vitamin D. Instead of 28 days only 18 days mechanical ventilation, instead of 29 only 19 on ICU, instead of 61% deaths only 36%.
