Table 5 Discrimination, reclassification, and calibration assessment of SCORE versus model adding clinical data

From: Disease activity influences the reclassification of rheumatoid arthritis into very high cardiovascular risk

  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  
  1. Clinical data represents age, dyslipidemia, hypertension, and DAS28-ESR
  2. p values in AUC rows represent the comparison between both AUC
  3. NRI and IDI are expressed as their values (95% confidence interval) and p value
  4. p value in H-L test expresses the p value of the Hosmer-Lemeshow chi-square statistical test
  5. Predictors are age, hypertension, dyslipidemia, and DAS28-ESR
  6. SCORE Systematic Coronary Risk Evaluation, AUC area under the curve, NRI net reclassification index, IDI integrated discrimination improvement
