"Patients from countries with high COVID-19 mortality rates, such as Italy, Spain and the United Kingdom, had lower levels..."

Correlation is not causation. "Sunlight availability" in Spain and Italy is higher than for the UK and especially Denmark, Finland and Norway, yet Italy and Spain have higher Covid than the UK, Denmark, etc. Without actual BLOOD MEASUREMENTS of Vitamin D3 levels and comparison with VIRAL LOAD the study is "less than valuable".
