Optimal cutoff value of TWSTRS for 18F-FDG PET/CT positive finding selected by receiver operating characteristics curve analysis. (A) The cutoff value of total score of TWSTRS was 27.5. The lowest total score of TWSTRS for the positive 18F-FDG PET/CT findings was 23. All subjects with a total TWSTRS of more than 39 showed positive 18F-FDG PET/CT findings. (B) The cutoff value of severity score of TWSTRS was 11.5. (C) The cutoff value of disability score of TWSTRS was 9.5.
