Results of the semi-quantitative percentage of immunopositive cells for galectin-3, galectin-4, galectin-7 or galectin-9 [labeling index (LI)] (A, B, C and E) and the quick score (QS) for galectin-8 (i.e., multiplication of the signal intensity score by the LI score) (D) for 10 cases of non-eosinophilic chronic rhinosinusitis (NECRS), 19 cases of eosinophilic chronic rhinosinusitis (ECRS), 9 cases of non-allergic nasal polyps (NANPs), 17 cases of allergic nasal polyps (ANPs), 29 cases of inverted papillomas (IPs) and 6 cases of squamous cell carcinomas (SCCs). Significant post-hoc comparison results are indicated by the lines (indicating the pairs of groups being compared) (*P<0.05, **P<0.01, ***P<0.001). The result of the Kruskall-Wallis test is indicated in the top-left corner of each frame.
