Pharma Research supports authors who want to share their work as widely as possible.

• Preprint (the version before peer review) – may be posted on a preprint server or personal site at any time. Please tell us when you submit.
• Accepted manuscript – may be deposited in an institutional or subject repository immediately after acceptance.
• Published version – because all articles are published under the CC BY 4.0 licence, the final PDF may be shared in any repository, including PubMed Central, institutional repositories, ResearchGate and Academia.edu, immediately on publication.

Please link to the article on the journal website and cite the published version.
