Fig. 2From: PET and CSF amyloid-β status are differently predicted by patient features: information from discordant casesa–d Relative predictive power of patient features for amyloid PET and CSF status. AUC-based variable importance (VIM) from 25 random forest models predicting PET status and 25 models from predicting CSF status are plotted. p values (***p < 0.001, **p < 0.01, *p < 0.05, ns non-significant) indicate the bootstrapped difference of VIM values between models predicting PET and CSF status using Wilcoxon signed-rank testsBack to article page
