The last diagram is not remotely the focus of the work. The first three are. It doesn't suggest anything and statements like that are not how science articles should be reviewed.
This article also wasn't exploring treatments for Alzheimer's. In this case I think they did a good job of identifying potential biomarkers for the disease.
Oh okay. I think I was too radical on my reply there. I think they did a great job too.
Too radical the other way! :P
They published some interesting work. Some worthy of further exploration. Some adding to their previous publications.
I will check out their works in depth. Glad to see you blogging again.
