Comparison of 5-year predicted survival rate and actual survival rate.

Training				Validation
Predicted survival rate	Total	Death	Actual survival rate	Predicted survival rate	Total	Death	Actual survival rate
>97%	143	2	98.6%	>97%	176	2	98.7%
90–97%	183	8	95.6%	90–97%	141	4	97.2%
80–90%	104	14	86.5%	80–90%	107	12	88.8%
70–80%	41	10	75.6%	70–80%	49	8	83.7%
60–70%	15	5	66.7%	60–70%	13	5	61.5%
50–60%	5	2	60.0%	50–60%	4	2	50.0%
<50%	14	11	21.4%	<50%	14	9	35.7%

The results of the calculations showed that in all subgroups of the training and validation sets, the actual survival rates matched the predicted 5-year survival rate intervals, except for the 70–80% group, where the actual survival rates were higher than the predicted survival rates.
