- The parameters included and score assigned to each variable for active CNO lesions. Adding up all parameters a maximum score of seven was obtained for each bone
- *In long bones the extension of bone edema < 25% was defined if one part out of five was involved, between 25 and 50% if two parts out of five were involved and of > 50% if three or more parts were involved. In complex bone and on the spine extension was defined as in CROMRIS scoring with 1 point an extension < 25%, 2 points an extension between 25 and 50% and 3 points with an extension > 50%
