Is vitamin D deficiency associated with the COVID-19 epidemic in Europe?

The authors have withdrawn this manuscript because, following comments received during the review process, they have updated the number of countries included in their study (and also changed from 5 to 10 years the limit for Vit-D information studies that they included), which led to non-significant correlations between mortality and infections and Vit D deficiency prevalence. Therefore, the authors do not wish this work to be cited as reference for the project. If you have any questions, please contact the corresponding author.
