High-sensitivity versus conventional troponin in the emergency department for the diagnosis of acute myocardial infarction

Table 1 Contingency data according to pretest probability^a

^aNet reclassification improvement (NRI) from the use of highly sensitive troponin T (HsTnT) was 7.9% (95% CI = 0.9 to 14.9; P = 0.034). Comparison of the model including HsTnT with cTnI was significant for low PTP patients (NRI = 10.3%, 95% CI = 1.9 to 18.7; P = 0.027), but NRI was not significantly different in moderate PTP patients (NRI = 11.6%, 95% CI = -0.5 to 23.7; P = 0.084) or in high PTP patients (NRI = -14.4%, 95% CI = -32.6 to -3.6; P = 0.181).
