Prediction model construction
fracture, heart disease, acute heart failure
CHRONIC HEART FAILURE, HEART DISEASE, ACUTE HEART FAILURE
Based on the above results of multivariate logistic analysis, we built a prediction model, Figure The nomogram of the risk of perioperative acute heart failure in older hip fracture patients. In this study, heart disease refer to history of heart disease (chronic heart failure excluded)Receiver operating characteristic curve of the modeling groupReceiver operating characteristic curve of the validation group
