Nomogram creation for predicting postoperative severe
ALI
Based on the characteristics of patients in the training group that were
predictive of postoperative severe ALI, a nomogram was developed. Eight
independent predictors of postoperative severe ALI were used (Figure 3).
Each factor in the nomogram received an individual score according to
the value of the factor, and a total score was obtained by summarizing
the scores of eight factors used to estimate postoperative severe ALI
risk. A bootstrap method with 1,000 repetitions was used to test the
nomogram, and a calibration curve revealing the probability that the
nomogram accurately estimated postoperative severe ALI risk was created
(Figure 4).
