Development and Validation of a Risk Prediction Model for Preoperative Frailty in Elderly Patients With Colorectal Cancer

Fried Scale and its related scales were used to analyze the status and risk factors of preoperative frailty in elderly patients with colorectal cancer. R software was used to construct a risk prediction model for preoperative frailty in elderly patients with colorectal cancer, and its validity and stability were verified in clinical practice.
