Fig. 3

A multi-nested sector statistical chart showing the weights of different level indexes. Each ring represents the indexes of one level. The area of each index within the ring of its level represents the percentage of its weight. The weight values of each index can be found in Table 3. A includes all the First-level and Second-level indexes and their weights. The inner ring represents the First-level indexes and their weights, while the outer ring represents the corresponding Second-level indexes and their weights. The blue part of the sectors represents the A1 Tooth movements indexes and its subordinate indexes, and the orange part of the sectors represents the A2 Dentofacial health and its subordinate indexes. B shows A1 Tooth movements, its Second-level indexes (the second ring), Third-level indexes (the third ring) and their weights. C shows A2 Dentofacial health, its Second-level indexes (the second ring), Third-level indexes (the third ring) and their weights
