Removing these two cases, the difference between the two sub-groups was highly significant ( χ 2 = 17.728, p = 0.0001, log-rank test) (data not shown).
Removing these two cases, the difference between the two sub-groups was highly significant ( χ 2 = 17.728, p = 0.0001, log-rank test) (data not shown).
The difference in the median survival time showed a borderline significance ( χ 2 = 3.248, p = 0.072, log-rank test) ( Figure 3 c).
