A retrospective cohort of 187 infants served as a training cohort; this included 56 BA and 131 non-BA patients. Serum MMP-7 testing model yielded an area under the receiver-operating characteristic curve (AUROC) of 0.916 [95% confidence interval (CI) =\u00a00.876\u20130.956], sensitivity of 94.6% (95% CI\u00a0= 85.1%\u201398.9%), specificity of 88.6% (95% CI\u00a0= 81.8%\u201393.5%), and accuracy of 90.4% (95% CI\u00a0= 85.2%\u201394.2%).
