As observed in Fig 4, for all patients, the sensitivity of the outcome variable ATC (activated T cellls) has shown to be consistently high throughout three time points (days 22, 112, 147) to the parameter c4 (maximum CD4+ T cell production rate stimulated by the interactions with tumor cells), since |PRCC(ATC, c4)| ≈ 1, i.e., magnitude of the Partial Rank Correlation Coefficient (PRCC) value of parameter c4 with respect to the output of interest ATC is close to 1. Here, CD4 is linked to neoplasm.
