Trying to put my finger on it but it smacks as some sort of double negative to the lay person (me). If you are saying that there is a lack of something, I think it's odd to say there is just as much of that thing rather than just as little of that thing.
I know, "at the same levels" doesn't itself state a higher or lower instance, but like I said for someone not used to reading this kind of conclusion, it jarred.
What's difficult to understand here?
