In follow-up communications, the editors of one of the three main multi-author textbooks examined in this paper have indicated that they plan to include conflict of interest information in a future edition and a second one is considering doing so. If anyone else knows of other textbooks in the biomedical or social sciences that currently disclose their conflicts of interest (like Stephen M. Stahl’s Essential Psychopharmacology) please email me or feel free to include it in the comments below.

Also, as Louis S Goodman (born in 1906) passed away in 2000, he should no longer be listed as the first author for citation #10. Apologies to Dr. Brunton. The correct citation of reference #10 should be:

Brunton LL, Chabner BA, Knollmann B. Goodman & Gilman's The Pharmacological Basis of Therapeutics, 12th ed. New York: McGraw-Hill, 2011.

Similarly, reference #12 was:

DiPiro JT, Talbert RL, Yea GC, Wells B, Posey LM. Pathophysiology: A Pathophysiological Approach. 9th ed. McGraw Hill Medical: New York, 2014.

but should be:

DiPiro JT, Talbert RL, Yea GC, Wells B, Posey LM. Pharmacotherapy: A Pathophysiological Approach. 9th ed. McGraw Hill Medical: New York, 2014.

The first sentence in the first full paragraph on page 7 was:

“There are some reasons to believe that the total remuneration reported in Fig 1A”

but should be:

“There are some reasons to believe that the total remuneration reported in Fig 3”.

If there are typos or other issues which were not caught earlier, please let us know.
