Figure 3From: Expression and prognostic significance of the polymeric immunoglobulin receptor in epithelial ovarian cancerDistribution of PIGR expression in histological subtypes. Box plots visualising (A) the staining distribution of PIGR in different histological subtypes and (B) in serous vs non-serous carcinomas. PIGR expression is described as cytoplasmic score, i.e. a multiplier of fraction (0-4) and intensity (0-3) of staining.Back to article page
