Radar plot of correlations between LOAD and 3D variables. Radar plot of the Pearson coefficients (R2) between LOAD and those 3D variables found significantly (p < 0.05) correlated. Corresponding lateral and 3D angles are reported sequentially to better detect relevant similar figures. LOAD correlations with dorsiflexion are marked in red, with plantarflexion in green. Correlations are referred to either the whole sample of patients (ALL, in grey), or to N (dark blue) or D (light blue) sub-groups. Line segments are used to highlight adjacent relevant results for the same variable of the same group: dotted lines represent the HLX region, thin solid lines represent the I MET region, and thick solid lines represent the II-IV METs region (V MET region did not show significant correlations). Correlations with R2 up to 0.30 were interpreted as weak, in between 0.30 and 0.70 as moderate, above 0.70 as strong
