Figure 4. Supplementary prognostic value of the qPCR score.

Figure 4

Each prognostic factor was used to divide the patient cohort in two different prognostic subgroups according to prognostic factors reported in Table 1. The qPCR score was then applied to all poor prognosis subgroups and good prognosis subgroups. (A) and (B) show the median TFS and median OS of the good prognosis subgroups, whereas (C) and (D) show the median TFS and median OS of the poor prognostic subgroups. The dotted line and error bar represent the mean and the SEM, respectively. Statistical differences were assessed using the Kruskal-Wallis test. Parts (E) and (F) show forest plots comparing the univariate Cox HR of the qPCR score with other prognostic factors for TFS and OS prediction, respectively. The hazard ratio (HR) of all variables was calculated by univariate Cox analysis and plotted with the 95% Cl on this forest plot. More details can be found in Table 2.
