Predictive value of serum procalcitonin for both initial and repeated immunoglobulin resistance in Kawasaki disease: a prospective cohort study

Table 6 The validity of PCT in predicting repeated IVIG resistance for the total group and the abnormal PCT group

Repeated IVIG resistance	Diagnostic test	Gold standard			Sen	Spe	PPV	NPV	Diagnostic accuracy	OR(95%CI)	P
