Characteristics of Websites Presenting Parenteral Supplementation Services in Five European Countries: A Cross-Sectional Study.

We aimed to characterize the parenteral supplementation services in Czechia, Ireland, Italy, Poland, and the United Kingdom based on their websites. We generated a list of websites by searching Google using the term "vitamin infusion" and selected cities with 250,000 citizens from each analyzed country. All search inputs were performed using the native language.
