Value of self-performed joint counts in rheumatoid arthritis patients near remission

Table 3 Agreement of patient defined remission with remission according to the ACR-EULAR definitions using the traditional evaluator derived joint counts (REF) ('gold standard').

	Boolean based without CRP		Boolean based with CRP		Index based CDAI*		Index based SDAI*
	Patient derived REM	Gold standard REM	Patient derived REM	Gold standard REM	Patient derived REM	Gold standard REM	Patient derived REM	Gold standard REM
Patients in REM	N = 25	N = 34	N = 22	N = 28	N = 30	37	32	37
Patients not in REM	n = 171	N = 175	N = 177	N = 181	N = 147	172	164	172
Positive Predictive Value	0.74		0.71		0.81		0.86
Negative Predictive Value	0.98		0.98		0.85		0.95
