Fig. 4From: Development of a novel tool: a nomogram for predicting in-hospital mortality of patients in intensive care unit after percutaneous coronary interventionThe calibration curve of the nomogram. a Training set, b validation set. The x-axis represents the in-hospital mortality risk predicted by the nomogram. The y-axis represents the actual in-hospital mortality rate. The diagonal dotted line represents the ideal prediction model. The solid line represents the prediction performance of the nomogram. The solid line is closer to the diagonal line, which shows that the nomogram has a higher degree of fitBack to article page
