Figure 1 shows the results of Kaplan-Meier survival analysis based on CD74 staining number. Tumor CD74 staining number (p = 0.020) and staining intensity (p = 0.020) both correlated significantly with a lower risk of death. As regards to other markers, there is no evidence of an association between those of expressions and OS in this cohort. The p-values for those markers were as follows; COX2 (p = 0.58), MIF (p = 0.29), mPGES1 (p = 0.19), iNOS (p = 0.99) and NT (p = 0.19), respectively (Figure S1). Here, NOS2 is linked to neoplasm.
