Cutoffs used it Rheumatology

The use of composite scores is wide-spread and cutoffs play an essential role in classifying the disease activity of patients

Rheumatoid arthritis

The composite measures are sorted alphabetically from left to right.

Cutoffs of the most commonly used composite measures for RA disease activity.

Disease activity	CDAI	DAS28CRP	DAS28ESR	SDAI
Remission	?	\(>\) 2.4	\(>\) 2.6	\(>\) 3.3
Low	?	\(\leq\) 2.9	\(\leq\) 3.2	\(\leq\) 11.0
Moderate	?	\(\leq\) 4.6	\(\leq\) 5.1	\(\leq\) 26.0
High	?	\(<\) 4.6	\(<\) 5.1	\(<\) 26.0

TODO: Add CDAI and sources for each column.

TODO: What about ACR70 etc criteria? These quantify the reduction of symptoms (e.g., tender joints) in percent from the baseline value (I assume, … the baseline part)
