Observed versus predicted NMR values for the training (MEC) and validation (CENIC, HSS, and METS) data. The predicted NMR is the averages of the predictions from the seven models (i.e., the ensemble model). The correlation between these values are displayed to the upper left of each scatterplot. The distribution of NMRs were different across studies, yet the correlations were still strong in the validation datasets
