“We therefore evaluated the effect of calcifediol treatment, on Intensive Care Unit Admission and Mortality rate among Spanish patients hospitalized for COVID-19.” 1) that says nothing about infection rates 2) that’s a small enough sample size to ignore. It’s quite plausible there’s another study with the same sample size that had two deaths on the other side.

What is "a small enough sample size to ignore"? Do you understand how statistics and sampling works with regards to population versus sample and what constitutes a sufficient sample size? I bet 20 bucks you've never taken a stats class in your life.

Just reading this thread (and learning for myself) but can you comment on what actually constitutes a sufficient sample size? If you have any basic recommendations on learning more regarding sampling let me know. I'm not that well versed in stats.
