Discrimination, reclassification, and calibration assessment of SCORE versus model adding clinical data

	SCORE	SCORE + predictors	p
Reclassification in patients with SCORE < 5%
Discrimination
AUC	0.766 (0.737–0.794)	0.775 (0.747–0.803)	0.23
Reclassification
NRI	-	0.07 (0.01–0.12)	0.018
IDI	-	0.07 (0.05–0.08)	0.000
Calibration
H-L test	0.35	0.80

Clinical data represents age, dyslipidemia, hypertension, and DAS28-ESR

p values in AUC rows represent the comparison between both AUC

NRI and IDI are expressed as their values (95% confidence interval) and p value

p value in H-L test expresses the p value of the Hosmer-Lemeshow chi-square statistical test

Predictors are age, hypertension, dyslipidemia, and DAS28-ESR
