I tried really really hard to put in all of the most significant studies on Vitamin D. Small, low-quality studies didn't make it in, but the major trials did.
To start, I appreciate your effort on this post. It looks like it took a lot of work and it does a great job of explaining difficult topics like why controls are important.
That said, I don't think it's fair to characterize the COVID study as low-quality. It's worth mentioning contrary results, even if it's an exception that proves the rule.
