Plots depicting predicted vs. measured values for CD68\(^+\)/ CD8\(^+\) ratio modelled by A random forest, B gradient boosted trees, C extra trees and D elastic net models prior to (i) and after (ii) feature selection. The red diagonal represents the trend line along which predictions would perfectly match the measured CD68\(^+\)/ CD8\(^+\) values. RMSE = root mean squared error.
