Logrank analyses of survival rates. The graph represents the Logrank analyses of survival rates of groups of treated and untreated CF mice and heterozygote (Het) littermates; The Logrank tests (low panels) show the statistical differences among survival curves. It shows that the cooling treatment used in this study didn’t impact the survival of the heterozygote CF mice, while improved the survival of CF mice significantly. Thus, the treatment does not appear to impact the animals negatively
