I want to know the answer to the following question:
What was the reason behind these interactions?
All the background I'm provided with is that "In contrast to this viewpoint, an article and associated editorial in the New England Journal of Medicine in May 2015 emphasized the importance of pharmaceutical industry-physician interactions for the development of novel treatments, and argued that moral outrage over industry malfeasance had unjustifiably led many to overemphasize the problems created by financial conflicts of interest.". Is that enough to answer the question?
Answer: no
