The studies aren't recent, but if anything has changed I suspect it is only that developer confidence has risen, not that test coverage has.

No the studies are not recent - and none of them are for people doing TDD. My experience, and the experience of others I've talked to doing TDD, is that code coverage goes way up when you do TDD.

This isn't really surprising since you should not be writing code with TDD that isn't being exercised by a failing test.

Now, if only somebody could find the time and money to do some research :-)

(and just to emphasise that I agree completely that TDD isn't all there is to testing :-)
