I’m no expert, but I’m highly skeptical of observational studies like this. The amount of confounding factors is almost limitless. Surely those that take vitamin D supplements are practicing better self care in general and less likely to, for example, be homeless? I didn’t see this accounted for in the paper. This analysis may justify a controlled study, but I otherwise don’t see it as important or interesting.

Getting yourself into an emergency doctors care through strange behavior, self harm, violence, exposure to the elements, would probably get you high dose vitamin D and B shots in the 1st world, and some of the US is part of the 1st world on a town by town basis.
