I have often wondered if the old advice that a good flow clears EFB is accurate. I wonder if starving hives whose brood is also starving just do a lot better once the nectar and pollen start coming in. Perhaps their trouble was not EFB at all but simple malnutrition?

>EFB shows up here in a few hives and yes it always seems to disappear with a good honey flow. Personally with EFB I have always thought that there is a nutrition aspect to the disease.  In addition certainly some forms of malnutrition (either quantity of nectar or quality of pollen) would produce something that looks like EFB as would (I now suspect but have no real lab data to prove) will some forms of fungicides < I see this latter quite a bit in commercial bees use for pollination work.
