Not very informative. No information, not even guesses, at what the "protective factors" might be. No details on where the males and females in question fall on the spectrum, beyond having a diagnosis or not, nor any information on how they made that judgment. And on top of that, a very small sample size. So, we really don't know if there are protective factors that females have, nor what they are if there are.
Reading those, I was thinking at first that, if this is so, I'm a defective female for lacking those "protective factors". But with further reading and thinking about it, it's also quite possible that the females in the study, the ones that it says don't have autism, are actually people like me.
