Fig. 6From: Patient-reported outcomes in a Chinese cohort of osteogenesis imperfecta unveil psycho-physical stratifications associated with clinical manifestationsProjections of later PROMIS outcomes to the PCA of the first PROMIS outcome. A Projections of children and adolescent’s later PROMIS outcomes (second, third or fourth) on the loading scores of the PCA of the first PROMIS outcomes. B Projections of parents’ later PROMIS outcomes (second, third or fourth) on the loading scores of the PCA of the first PROMIS outcomes. Arrows point from the PROMIS outcome at one time-point to the next, for each patient. Arrow colors indicate the original states in the first PROMIS. The transition diagrams at the bottoms of A, B show the numbers of state changes for each pair of successive PROMIS surveys. The numbers on the edges show the numbers of patients or numbers of times a patient changes from one state to another (or the same) stateBack to article page
