It was a rhetorical question since anyone who knows about the scientific method would realise a control is not necessary for this kind of study. You show the same level of scientific ignorance as Dangerous Goods! If you want to make criticisms of the Science I suggest you learn some first!
This article shows that green blobs are not gallstones. How can you argue otherwise? Rubbish about "controls" doesn't cut it. There IS no control and I have never said there is. If you knew what a control was for, you would realise why one is not necessary.
I'm not sure where your comments about the scientific method come from - I am quite conversant with the scientific method, as my posts will verify. You however are not.
Can you understand what I'm saying - there IS no control because a control is not needed.
