Key result
The AxSYM BNP assay demonstrated comparable diagnostic accuracy to the ADVIA Centaur BNP assay for diagnosing congestive heart failure in patients with dyspnea (AUC 0.938 vs 0.932; P=0.265).
Why the study?
Does the AxSYM BNP assay have comparable diagnostic accuracy to the ADVIA Centaur BNP assay for detecting congestive heart failure in patients presenting with dyspnea?

Mean Difference: 0.007 (95% CI -0.005–0.019)
Absolute Event Rate: 0.938% vs 0.932%
p-value: p=0.265
The AxSYM BNP assay demonstrates comparable diagnostic accuracy to the ADVIA Centaur BNP assay for identifying congestive heart failure in emergency department patients with dyspnea, despite proportional differences in absolute values.
Mueller et al. (2004) conducted a cross-sectional in Dyspnea (Congestive Heart Failure) (n=100). AxSYM BNP assay vs. ADVIA Centaur BNP assay was evaluated on Diagnostic accuracy for congestive heart failure (Area under the ROC curve) (Difference in AUC 0.007, 95% CI -0.005 to 0.019, p=0.265). The AxSYM BNP assay demonstrated comparable diagnostic accuracy to the ADVIA Centaur BNP assay for diagnosing congestive heart failure in patients with dyspnea (AUC 0.938 vs 0.932; P=0.265).
