The phrase "a difference of survival" is correct and usable in written English.
It can be used in contexts discussing varying outcomes or conditions that affect survival, such as in discussions about species, ecosystems, or human situations.
Example: "In the harsh environment of the Arctic, there is often a difference of survival between species that can adapt and those that cannot."
Alternatives: "a matter of survival" or "a question of survival."
Two studies by Park et al. [85, 86] compared the survival of patients with uterine sarcoma with (n = 48) and without morcellation (n = 58) during surgery and demonstrated a significant difference of survival in favour of the non-morcellated group (Table 5).
Cross-period comparisons without considering the overall binary adherence index showed a significant difference of survival rates of approximately 7 % (see subsection 'Cross-period results').
The data showed a significant difference of survival rate among these four treatment protocols (Log Rank = 8.445, df = 3, P = 0.038).
However, such a significant difference of survival between patients with G ≥ 2 anemia and those with G0 or 1 anemia was well maintained in analysis of DFS instead of EFS (P < 0.001; Fig. 1c).
A significant difference of survival years was found between the three lifestyle intervention strategies and the other two groups at the initiation ages of 25 and 40 years, but not at 60 years.
This result is consistent with data comparing groups of mice instilled simultaneously with P. aeruginosa and C. albicans or with P. aeruginosa alone showing a significant difference of survival in favor of the C. albicans-colonized group at Day 7 [ 23].
This study was powered to detect a difference of 5% in survival rates for women and men across 3 places and 3 poverty groups with 80% power at a 2-tailed significance level of 5% [ 48, 49].
9 studies [31], [33], [35], [40], [42], [43], [49], [54], [55] did not find a statistically significant difference of survival functions and 11 studies did not report a significance test.
5 studies reported a statistically significant difference of survival functions in favor of HSCT [38], [47], [48], [50], [51] and 1 study in favor of IST [46].
