Extended Data Fig. 4: Visualization of extracted measurements from gait videos with respect to cohort (PD vs. CTRL) and gait impairment score within the PD cohort.
From: Data-driven discovery of movement-linked heterogeneity in neurodegenerative diseases
For each metric, the left plot compares metric values across the Healthy/Control group and the PD group. The right plot compares the metric values across different levels of gait impairment severity (MDS-UPDRS 3.10) among the PD group. On each box, the central line indicates the median value, and the top and bottom edges indicate the 75th and 25th percentiles, respectively. The whiskers extend to 1.5 times the interquartile range, and data points beyond the whiskers are represented using the ♦ symbol. For plots with statistically significant metric values between groups (P < 0.05 from two-sided t-test for left plots and P < 0.05 from Kruskall-Wallis for right plots), each group mean value is overlayed as a × symbol, and dashed lines connect the mean group values. For plots without statistical significance, the overall metric mean across all groups is drawn as a dashed line.
