Fig. 2: Results of hypomimia sensitivity analysis.
From: Automated video-based assessment of facial bradykinesia in de-novo Parkinson’s disease
(A) Receiver operating characteristic curves between PD and controls. The solid line represents automatic assessment with the best overall AUC, which was based on the five facial areas with the best discrimination scores. The dashed line represents the operating characteristic curve based on the 4-point perceptual assessment. B Ratios of participants manifesting abnormal patterns in different numbers of affected areas. C Ratios of disrupted facial areas in PD.
