Fig. 3From: Predicting the risk of acute kidney injury after cardiopulmonary bypass: development and assessment of a new predictive nomogramCalibration curve for nomogram prediction of AKI after CPB in the cohort. The x-axis represents the predicted risk of AKI after CPB. The y-axis represents the actual occurrence of AKI after CPB. The dotted line on the diagonal represents the perfect prediction of the ideal model. The solid line represents the performance of the nomogram. The closer the fit to the diagonal dashed line is, the better the prediction effectBack to article page
