  1. (a) Values indicate the correlation coefficient between each region. MFTJ refers to the medial femorotibial joint, which includes the MFC, MFP, MTA, MTC, and MTP (see Fig. 3). (b) Probability in each region
  2. High correlation values and corresponding probabilities that should be focused were shown in italics for quick recognition
