Proportion of joints with damage, grouped by TIV of PD scores of individual joints. Among the 12 joints with a TIV-individual PD score of ≥16, erosion had progressed in 7 joints (58.3%), JSN in 6 joints (50%), and total Sharp score in 7 joints (58.3%). Among the 46 joints with a positive TIV-individual PD score of <16, only 1 joint developed new erosion. No progression was seen among any of the joints with a TIV-individual PD score of 0
