Table 2. In vitro naïve T cell proliferation correlates with magnitude of response to immunization with neoantigen, but not prevalent antigen.
The table represents the correlation matrix between in vitro T cell proliferation and response to immunization; data are Spearman’s correlation coefficients (P value). Note lack of correlation with response to TT (a recall antigen), but significant correlations with DTH and antibody response to KLH (a neoantigen).
In vitro T cell proliferation | Response to KLH immunization |

As stimulation index
As mm of induration at maximum diameter
As U/mL
As % of Vβ3 or Vβ5+ cells that expand after stimulation with the corresponding agonistic antibody
