Other issues with the commercial running of RCTs can include patients enrolling in multiple trials at once (apparently some people even treat it as a very low-paid career), lying about symptoms to not get kicked out, etc. GIGO.

Does intervention X work for homeless people with problem Y? Who knows, they were excluded from the RCT. But most of the population with Y is homeless.
