Multivariable Cox regression analysis (Table 2) showed that stronger expression of COMP in the stroma (p < 0.001, HR: 2.03, 95% CI 1.33–3.1) and more advanced clinical FIGO stages (p < 0.001, HR: 2.51, 95% CI 1.52–4.13) were independent predictors of shorter OS, whereas COMP expression in cancer cells was not prognostic. Here, COMP is linked to cancer.
