Table 1 The diagnostic accuracy of PE findings for the detection of AVF stenosis

From: Quantification of the severity of outflow stenosis of hemodialysis fistulas with a pulse- and thrill-based scoring system

  Abnormal thrill Abnormal pulsatility PESOS Critical PESOS
Degree of stenosis detected > 50% stenosis > 50% stenosis ≥75% outflow stenosis ≥82% outflow stenosis
Sensitivity 33% 70% 80% 81%
Specificity 71% 67% 79% 82%
PPV 61% 74% 85% 57%
NPV 44% 62% 72% 94%
  1. PPV positive predictive value, NPV negative predictive value
