Nomogram for estimating the risk of SSI in patients. Nomogram for PCa patients to predict the risk of SSI. SSI, surgical site infection; FPG‐CV: variation coefficient of fasting plasma glucose; MFBG: mean fasting blood glucose. The method of using the nomogram is as follows: all variables (Duration of diabetes, Blood glucose control scheme, Number of fused vertebrae, Duration of drain placement, preoperative MFBG, preoperative FPG‐CV, postoperative FPG‐CV) of the patient can get a specific score on the Points‐axis of the nomogram. Add the corresponding scores of all variables to get the total points. The total score of each patient can be obtained through the corresponding relationship between the Total Points‐axis and the Risk of SSI‐axis to get the specific upgrade risk
