From: Feasibility and validity of telephone triage for adverse events during a voluntary medical male circumcision campaign in Swaziland

Characteristic Diagnosed as moderate or severe AE by VMMC site clinicians Diagnosed as not moderate or severe AE by VMMC site clinicians Total  
Diagnosed as moderate or severe AE by telephone triage 43 9 52 Positive predictive value = 82.7%
Diagnosed as not moderate or severe AE by telephone triage 19 18 37 Negative predictive value = 48.6%
Total 62 27 89  
  Sensitivity = 69.4% Specificity = 66.7%
