If I see a title with 'evidence-based' in it, I have a good guess at what sort of methodology and epistemology I expect to see in it: systematic review with a focus on randomized trials & meta-analyses. This gives me a good start at interpreting it (positive results should be taken seriously, but nulls are not very informative because typically there is little acceptable data; cost-benefit reasoning will likely not be included).

While if a title includes 'rational' in it...

Erm, yes I think so too, I don't know why I offered that. I'm retracting the whole comment, it seems unnecessary.
