SCGB3A2 and chronic rhinosinusitis without nasal polyps: Analyzing the relationship between SCGB3A2 (UGRP1) staining intensity and the number of inflammatory cells, we found that SCGB3A2 (UGRP1) staining intensity inversely correlated with the number of total infiltrating cells (r = -0.485 and -0.558 in the CRSsNP and CRSwNP group, respectively; P < 0.05 for both), but did not correlate with the number of eosinophils or mononuclear cells.
