Immune phenotype and survival probability
We detected a positive correlation between the leukocyte concentration and the risk to die at a given age (Table 3). Moreover, we found that the relative number of neutrophils was positively correlated, while the relative number of lymphocytes was negatively correlated, with the risk of death (Table 3). The relative numbers of monocytes and eosinophils were not correlated with the risk to die (Table 3).
