The sensitive (Se) and specificity (Sp) of predicting complications. (a) Se versus 1-Sp based on the oxygen saturation (S) dropping below a threshold Sth at either the completion of the conduit (surgical step 4) or the completion of the anastamosis (surgical step 5). The threshold value of S used as a discriminator (Sth) was increased in incremental steps, and the data at Sth = 0.230 are shown as a solid circle. (b) The Se versus 1-Sp based on the blood content (B) dropping below a threshold Bth at either surgical step 4 or 5 yields Se = Sp = 0.57 when Sth = 0.0127.
