In the ROC analysis performed for the diagnostic performance of abscess formation in AP, the sensitivity of the GCF sclerostin and GCF PGE2 tests was determined as 65.5% and 72.7%, specificity as 98.6% and 68.6%, and AUC as 0.768 and 0.712, respectively (p < 0.0001). Here, SOST is linked to alkaline phosphatase measurement.
