Simulated Yield for Dysplasia within Any Samples for a Given Patient under Selected Classical and Novel Biopsy Regimens by Segment Length. Biopsy regimens missed dysplasia in simulations of shorter segments because of less total biopsies introducing the possible of missing a single dysplastic biopsy fragment at random. All regimens performed well among longer segments. Note that q2cm regimens' sensitivity tended to drop slightly at even numbered segment lengths because the same number of biopsies was performed over a larger area compared to a segment one cm shorter.
