We got a statistically significant model (p < 0.001, Chi-Squard 94.1, Cox & Snell R2 = 0.244, Nagelkerke R2 = 0.453) identifying three variables as potential predictors for dMMR: CRC located in the ascending colon and CDX2 expression loss are positive potential predictors while CRC located in rectum is negative potential predictor for dMMR (Table 3) [91.37% of all cases were correctly classified (Hosmer and Lemeshow test, p = 0.512)]. This evidence concerns the gene CDX2 and colorectal carcinoma.
