Differences in MUC5AC (a), MUC6 (b), αGlcNAc (c), TFF2 (d), the ratios of αGlcNAc to MUC6 (e) or the ratios of TFF2 to MUC6 (f) expression scores between low- and high-grade PGA are compared. Data are represented as means ± SEM (a–d) and as violin plot (e, f). *P < 0.01, **P < 0.001 ***P < 0.0001 by the Wilcoxon matched-pair test (a–f).
