SFRP Immunolabelling: Semi-Quantitative Gradinga.

aSemi-quantitative grading = Intensity+% immunolabelling (minimum = 0 and maximum = 6):Intensity of Immunoreactivity.0 = no staining.0.5 = very weak.1 = weak.2 = moderate.3 = strong.% Immunolabelling.0 = 0%.1 = 1% to 10%.2 = 11% to 50%.3 = >50%.bSignificance.cSFRP1, 2 and 3 expressed in keratocytes only; SFRP5 expressed in stroma including matrix and cells.dMann-Whitney test, peND - not detected.fKC full thickness graft n = 7/15; deep anterior lamellar keratoplasty (DALK) n = 8/15.
