Mean and standard deviation values for each metric in each cohort is reported. Column “Final rank” represents rank of model based on sum of individual ranks (details in Supplementary material table S2). CorrSigNIA ranks second in cohort C1-test, closely following another CorrSigNIA variant, whereas it ranks first in cohort C2.
