I used medical-physics.csl via Paperpile in Google Docs.

I've been working on a revision of a manuscript to Medical Physics, addressing comments of the reviewer about missing DOIs/URLs for some of the references, and first I thought I would need to change the csl to add DOI/URL. However, that turned out to be far from trivial, and so I turned back to the Medical Physics submission guidelines, which state unambiguously that

References should follow standard American Medical Association (AMA) Style.

I then was able to switch to AMA via american-medical-association.csl, and had my problem solved.

This led me to think that medical-physics.csl is not needed, and in fact creates confusion, since it omits URLs/DOIs that are often really critical.

medical-physics.csl was added in this commit on Sept 16, 2012.

But american-medical-association.csl was added back in Dec 18, 2010 as ama.csl, and later renamed.

I believe medical-physics.csl should be removed, or should be replaced with the content of american-medical-association.csl.
