From: Clinical significance of stromal ER and PR expression in periampullary adenocarcinoma
Distribution of hormone receptor positive stromal cells in relation to tumor origin and morphology. Box plots illustrating the distribution of stromal cells expressing ER (a, c, e) and PR (b, d, f) among the five different tumor origins, in the entire cohort (a-b), in women (c-d) and in men (e-f). P-values were measured with non-parametric test. Sample immunohistochemical images of stromal ER and PR expression, respectively, are shown in panels (g and h)
