AUC for receiver‐operating characteristic curve analysis for horses with inflammatory versus noninflammatory, and systemic versus local inflammatory disease. When comparing SAA, fibrinogen and iron, the only significant difference in AUC was found for SAA versus iron (P = .0016) for inflammation versus noninflammation.

Analyte	Inflammatory Versus NonInflammatory Disease	Systemic Versus Local Inflammation
SAA	0.83 (0.77–0.89)	0.80 (0.72–0.89)
Fibrinogen	0.79 (0.72–0.75)	0.63 (0.52–.075)
Iron	0.71 (0.63–0.78)	0.73 (0.63–0.83)
MPXI	0.51 (0.43–0.59)	0.53 (0.40–0.65)

95% confidence intervals in parentheses.

AUC, area under the curve; SAA, serum amyloid A.
