Exploratory analysis of the effect of varying the cTF cutpoint on the hazard ratio for the TF high versus TF low groups in univariable Cox proportional hazards models. Cutpoints between 1% and 20% are tested in increments of 1% in (a) mCRPC, (b) mBC, (c) aNSCLC, and (d) mCRC. The dotted line shows a hazard ratio of 1. Behind each plot of hazard ratios is a histogram of TF values between 1% and 20%, expressed as a percentage of all patients per disease. The full histogram is presented in Supplementary Figure S2, available at https://doi.org/10.1016/j.annonc.2022.09.163.
aNSCLC, advanced non-small-cell lung cancer; mBC, metastatic breast cancer; mCRC, metastatic colorectal cancer; mCRPC, metastatic castration-resistant prostate cancer.
