DOF: entrance vs exit pupils and pupil magnification.

If two lenses have the same effective focal length for a given focus distance, will the resulting photos have the same DOF (for the same CoC)?

If so, is it fair to say that the differences in DOF are (equivalently) due to the differences in effective focal length?  If not, how much of the difference in DOF is attributable to the differences in effective focal length vs other factors?
