Coronary calcium score improves the estimation for pretest probability of obstructive coronary artery disease and avoids unnecessary testing in individuals at low extreme of traditional risk factor burden: validation and comparison of CONFIRM score and genders extended model

Table 2 Discriminations of CONFIRM score and GEM in individuals with 0 and 1 RF

AUC area under the receiver operating characteristic curve, IDI integrated discrimination improvement, CI confidence interval, other abbreviations as in Table 1
^aObstructive CAD was defined as present if an individuals had at least one lesion with ≥50% diameter stenosis or any non-assessable segments due to severe calcification on CCTA
^bCompared to CONFIRM score, the IDI of GEM = [P(GEM|Positive)- P(GEM|Positive)]-[P(CONFIRM score|Negative)- P(CONFIRM score|Negative)]
