CLASSIF1 Classification |
- The database of the ongoing trial contained 724 patients
(July 2001)
with 159 2-year survivors, 404 2-year nonsurvivors, 161 < 2-year still
surviving patients, 25 5-year survivors, 442 5-year nonsurvivors and
257 < 5-year still surviving patients. This means that 563 patients
were included in the 2-year classifications and 467 patients in the
5-year classifications. 5.6% and 1.9% of the included patients could
not be classified due to ambiguous classifications.
- The first 300 included patients were used
as learning set while the remainder of the patients served
as unknown test set.
- Prospective classifications were obtained for the patients
not fulfilling the inclusion criteria (161 < 2-year and
257 < 5 year still surviving patients)
- The classification indicates that 5-year non survivor patients
are detected with a predictive value of 100% in the learning set
while the predictive value is 15.1% for 5-year nonsurvivors
(fig.2a) No 5-year survivors were contained in the test set
(fig.2b) while the 5-year survivors classified better than in
the learning set.
- The predictive values for 2-year non survivors was 88.6%
and 38.9% for 2-year survivors (fig.2c). The unknown
test set classified similarly as the learning set (fig.2c).
