Figure 1

Overall survival curves according to the total Cat X values in serum from patients with CRC. The number of patients at risk at 0, 24 and 48 months is shown below the axis for each stratum and the number of deaths (events) is shown to the left. The difference between the strata was tested using the log rank test. (A) Kaplan-Meier estimates of survival for patients with stages I-III who did not receive chemotherapy. Cat X has been grouped using tertiles (denoted 0, 1, 2) (B) Kaplan-Meier estimates of survival for patients with stage III who, 0: did not receive chemotherapy and had low Cat X, 1: did not receive chemotherapy and had high Cat X, 2: received chemotherapy and had low Cat X, 3: received chemotherapy and had high Cat X.
