RIF1 and neoplasm: As previously observed for several different experimental models and drugs, including everolimus [7], the change in T1 (ΔT1) was highly significantly (p = 0.0032) positively correlated with the change in RIF-1 tumour volume (ΔTVol), see Figure 4A, but there was no significant correlation between ΔCho/H2O and ΔTVol.
