    We thank Dr Boers for the reflections1 on the results of our ACR/EULAR endorsed work on the revision of the remission criteria for rheumatoid arthritis (RA).2 The main aims of this collaborative project were to validate the previously provisionally endorsed index-based remission criteria3 using the Clinical Disease Activity Index (CDAI) and Simplified Disease Activity Index (SDAI) and to adapt the Boolean definition to identify a more harmonised group of patients in remission. Through this procedure the interdefinition heterogeneity could be reduced.

    In our analyses on the revision of the ACR/EULAR Boolean remission criteria, we embraced the Patient Global Assessment (PtGA) instrument as a continuous scale from 0 to 100 mm Visual Analogue Scale (VAS), based on the format used in the original clinical trial data underlying the …
