Assessment of performance of survival prediction models for cancer prognosis

Table 4 The 97 total patients were randomly split into a training set and a test set

Model	Single Group Analysis	High- versus Low-Risk Group Analysis
Model	Cox Model I	Cox Model II	Log-rank test
A	0.7630	0.5032	0.5164
B	0.5408	0.4628	0.4778
C	0.2876	0.2844	0.2964
D	0.5810	0.4286	0.4382
E	0.3302	0.2600	0.2702

The numbers of patients for the training and test sets were 49 and 48, respectively. The values are the proportion that the estimated p-values were less than or equal to 0.05 from a total of 10,000 computations, based on 5,000 randomly splits.
