In addition, Spearman correlation analysis showed that p53, Ki-67, and PAS staining showed no correlation between glycogen in Non-NSL, and abnormal expression of p53 and Ki-67 was significantly positively correlated in the process of dysplasia to early carcinogenesis (rs = 0.671, 0.770, 0.683, p < 0.05), and p53, Ki-67, and PAS staining were significantly negatively correlated with each other at LGD (rs = −0.598/−0.535, p < 0.05), but had no correlation with HGD to early cancer (rs = 0.355, 0.378/0.274, 0.258, p > 0.05) (Supplementary Table 1 and 2). Here, MKI67 is linked to cancer.
