Numbers correlate to the number of specimens staining positive at 0, 1+, 2+, or 3+ intensity. % refers to the percentage that is positive for 1+ or higher staining.
ECs indicates endothelial cells.
Percentage of specimens with moderate (2+) or strong (3+) staining.
n = 39 as no endothelial cells were seen in either slide.
