No it is not.
As was pointed out to you earlier, the authors of this garbage didn’t do ANY RESEARCH AT ALL.
They composed a position using other people’s research reinterpreted to mean what they desired it to mean.
MrEdd, you are correct. This study being reported isn’t original research that stands on its own. It is rather a pseudo-study of a collection of prior studies of indeterminate validity. To put this ‘study’ in the category of ‘research’ simply because some type of ‘analysis’ of whatever data was chosen is in my opinion nothing more than convenient subjective manipulation and pre-conceived interpretation of convenient sets of data.
