The phrase "a small difference in survival between" is correct and usable in written English.
It can be used in contexts discussing comparative studies, research findings, or statistical analyses related to survival rates in various scenarios.
Example: "The study revealed a small difference in survival between the two treatment groups, suggesting that both methods are effective."
Alternatives: "a slight variation in survival among" or "a minor disparity in survival between".
Our study may have been underpowered to detect the small difference in survival between these two groups.
There is very little difference in survival between affluent and deprived lung cancer patients, because the prognosis is so poor, so the deprivation gap in survival is very small, regardless of the life tables used.
Small differences in survival estimates between stage groups are more likely to be statistically significant in a large data set.
Despite the size and other favorable characteristics of the current study, the prevalence of protein positivity for the apoptosis pathway markers examined was low (≤ 15%) and the differences in survival between protein expression positive versus negative groups were small, resulting in only limited power (<10%) to distinguish the small differences in survival actually observed between groups here.
Small differences in survival can translate into large differences and therefore a larger significance during a course of multiple treatments.
In the absence of methylation of the MGMT promoter, there was a smaller and statistically insignificant difference in survival between the treatment groups [ 4].
However, while protecting against death from acute cardiac decompensation precipitated by ritonavir, exenatide does not completely prevent it, as shown by the small but significant difference in survival between animals given exenatide and ritonavir or exenatide alone.
Although the numbers are small, there was no difference in survival between patients with COX-2 positive and COX-2 negative tumours who received adjuvant treatment.
This shows a significant but small difference in the probability of survival between the cemented and uncemented groups.
