need help finding a study

When I had my appt last week, my GI mentioned a study he read about patients with pancolitis being able to achieve remission easier than those with left-sided colitis.

I've tried a few searches, but haven't been able to find it...  Any of you internet savy peeps up for looking???

That's the only one I could find, too. But I seem to remember the one you're looking for. I have no idea where it is though.
