Evaluation results of AI-PBPK model-predicted tumor delivery efficiency. A global evaluation of goodness of model fit between the data-driven (x-axis) and AI-PBPK model-predicted delivery efficiency (DE) (y-axis) at (A) 24 hours, (B) 168 hours and (C) the maximum DE. Abbreviations: %2e and %3e, represent the percentage of data points within 2-fold and 3-fold errors, respectively; Adj-R2 and RMSE represent the adjusted determination coefficients and root mean square, respectively.
