Furthermore, we investigated the tendency of over-and under-prediction of RRF-BP in each tissue type. The results are also shown in Table where it can be seen that values for the adipose, brain, and gut tissues were overpredicted. By contrast, values for the heart, kidney, and liver were underpredicted. Hence, we can conclude that the predictive model for each tissue has good accuracy and prediction tendency, which must be understood before using it in the practical drug discovery process.
