Considering the first 24 hours after surgery sensibility was 100% (IC: 76.84 to 100%),
while specificity 100% (IC: 47.82 to 100%),
VPP 100% (IC: 76.84 to 100%); NPV 100% (IC: 47.72 to 100%).
From25 to 48 hours after surgery variables respectively were: sensibility 91.70% (IC: 76 to 99.80%),
while specificity 100% (IC: 19.41 to 100%),
VPP 100% (IC: 58.72 to 100%); NPV 75% (IC: 19.41 to 99%).
From 49 to 72 hours and >73,
doubtful cases were presented,
and the variables were calculated considering them positive or negative.
From 49-72 hours,
considering positive the doubtful cases,
sensibility was 83.30% (IC: 36 to 99),
specificity 100% (IC: 15.81 to 100%),
PPV 100% (IC: 47.82 to 100%),
NPV 66.67% (IC: 9.43 to 99.16%).
Considering negative the doubtful cases,
sensibility was 16.67% (IC: 0.42% to 64.12%),
specificity 100% (IC: 16.00 to 100%),
PPV 100 % (IC: 2.5 to 100%),
NPV 28.57% (IC: 3.67 to 70.96%).
>73 hours,
considering positive the doubtful cases,
sensibility was 77.78% (IC: 39.99 to 97.19%),
specificity 100% (IC: 45.00 to 100%),
PPV 100% (IC: 59.04 to 100%),
NPV 33% (IC: 0.84 to 90%).
Considering negative the doubtful cases,
sensibility was 22.22% (IC: to 48.25%),
specificity 100% (IC: 0.02 to 100%),
PPV 100 % (IC: 15.80 to 100%),
NPV 0.12% (IC: 0.00 to 52.70%).
