Notes: The above estimates and p-values are for the base model with baseline CIPN8, cumulative dose, relative dose intensity and Tc>0.05. Both Tc>0.05 and Cmax are in standard deviation units. The clinical variables (age, race, alcohol, and diabetes) were first tested individually for their contribution to the base model, and if p<0.10 were included in the multivariable model. The outcome of the model is the square root of the CIPN8 score. These models included an intercept estimate with no meaningful interpretation, thus the intercept data are not shown. Significant p-values (<0.05) are bolded
