Yes, the study looks very good. The number of patients (76) is not large, hence "pilot". Other than that - solid evidence, as good as it gets. Fwiw, in England/UK, there is a permanent recommendation to supplement Vitamin D b/c of endemic deficiency, given out by the public health bodies: Public Health England (PHE) (https://www.gov.uk/government/news/phe-publishes-new-advice-on-vitamin-d https://www.gov.uk/government/news/phe-publishes-new-advice-...) and NICE (https://www.nice.org.uk/guidance/ph56 https://www.nice.org.uk/guidance/ph56). This is not strictly Covid-19 related, it predates it. I understand earlier in the year NICE urgent review of available evidence found the evidence wanting: of low quality and insufficient (https://www.gov.uk/government/news/insufficient-evidence-for-vitamin-d-preventing-or-treating-artis https://www.gov.uk/government/news/insufficient-evidence-for...). I wonder if they will re-review in light of more evidence put forward recently. Given the balance of likely costs of intervention (Vitamin D is safe, cheap, prior knowledge that good portion of population are deficient, prior knowledge it helps in respiratory illness) versus not (major pandemic) if I were a temporary benevolent dictator, would institute a mass public supplementation programme.
