Tumor subtype-related comparison of IRS SST2 distribution in all (A), male (B) and female (C) cases. Graphs: median with interquartile range; each individual point represents a tumor: circles represent FSH tumors, down-pointing triangles FSH-LH tumors, and up-pointing triangles LH tumors. (A). Statistical test: Kruskal–Wallis, p = 0.01, n = 21, 72, 4, with Dunn’s test for columns comparison. (B). Statistical test: Kruskal–Wallis, p = 0.15, n = 8, 52, 4. (C). Statistical test: Mann–Whitney, p = 0.01, n = 13, 20. Abbreviations: immunoreactive score (IRS), somatostatin receptor 2 (SST2), follicle-stimulating hormone (FSH), luteinizing hormone (LH), not significant (ns), p < 0.05 (*).
