^aData obtained from proteomic analysis were used for investigating dose prediction. Ranks and specific values of all models were provided in Supplementary Table S4.

^bCoefficient, R² and p value was obtained by linear regression analysis for predicted vs. actual doses.

^cMAE values were used as indicators to compare the difference between actual irradiated and predicted dose.
