Restricted Cubic Splines (RCS) Analysis: The association between the stress hyperglycemia ratio (SHR) and all-cause (A) and cardiovascular mortality (B) in patients with chronic kidney disease (CKD). In patients with CKD and diabetes, the relationship between SHR and all-cause mortality (C) and cardiovascular mortality (D) was adjusted for age, sex, race, education level, marital status, serum cotinine, body mass index (BMI), smoking status, hypertension, hyperlipidemia, and cardiovascular disease. The solid line and shaded region represent the estimated values and their corresponding 95% confidence intervals (CI), respectively. SHR, stress hyperglycemia ratio; BMI, body mass index; CI, confidence interval; HR, hazard ratio
