Nomogram of the pcMPO-AF rule for POAF risk prediction. The prediction is based on the following logistic model: logit(POAF) = − 4.521 + 3.086× (pericardial MPO at post-op 6 h ≥ 389,054.9) + 2.775 × (IABP use) + 2.022 × (serum MPO at baseline ≥ 163.7) + 1.481 × (left atrial diameter ≥ 56.5) + 0.928 × (age ≥ 66.5), where each predictor is coded as 1 if the criterion is met or 0 otherwise. The nomogram can be used by determining the position of each variable on the corresponding axis, drawing a line to the point axis, and adding points from all variables. Next, a line was drawn from the total point axis to determine POAF probabilities using the bottom line of the nomogram. Abbreviations: MPO, myeloperoxidase; POAF, postoperative atrial fibrillation; IABP, intra-aortic balloon pump.
