Table 1. Histology scoring table for sample quality.

Score	Quality	Features
0	poor	portions of sample missing or disrupted by tears or clefts; overall architecture distorted at low magnification
1	fair	all architectural features intact; may have several small artifacts (distortion, peripheral portions of tissue lost) that do not impede evaluation
2	good	as 1, but artifacts attributable to collection are rare
3	excellent	no artifacts attributable to collection observed
