The number of usable subject pairs n u, the number of concordant subject pairs n c and the number of tied subject pairs n t are: (6) n u = ∑ i ∑ j I y i < y j n c = ∑ i ∑ j I y i < y j and y ^ i < y ^ j n t = ∑ i ∑ j I y i < y j and y ^ i = y ^ j For time-to-event outcomes y, pairs of subjects are usable if their survival times are not equal and at least the smallest survival time is uncensored.

Participants identified the smallest improvement in survival time or survival rate they judged necessary to make adjuvant endocrine therapy worthwhile.
Branch m3 was associated with a rather small decrease in survival time because the red cluster splits in distinct two subtypes with a successive second increase (branch m5) or a decrease (branch m4) in survival time, with branch m4 leading to the majority of the red cluster, which had the lowest survival time of all four clusters.
The latter result is unsurprising, because of the very low number of deaths registered in these small populations during a survival time frame which is shorter than that observed in breast cancer patients managed with the currently available multimodality treatments.
The small racial difference in survival time of approximately 2 weeks is not clinically meaningful.
Among patients of small HCC, the median survival time was 12 months and the 1-year survival rate was 88.1%.
However, the success of their use is limited by effectiveness only in a restricted population, potential development of lethal resistance with vemurafenib treatment, and only a small increase in median survival time in the case of ipilimumab [ 6].
While the amount of additional survival time is small, researchers called the progress significant.
We will use this model to predict the impact of a mutation that leads to deposition of small amounts of fat on survival time.
Alternatively, there are no published studies that have analysed the association between polymorphisms in MMPs and survival time for small cell lung cancers (SCLC).
Notably, it was shown in patients with advanced non-small cell lung cancer that the survival time of amphiregulin-negative patients treated with gefitinib was significantly longer than that of amphiregulin-positive patients.
