(B) Restricted cubic spline analysis of mBMI and the Log-Transformed OR for in-hospital mortality. (C) Restricted cubic spline analysis of mBMI and the OR for postoperative cerebral infarction. (D) Restricted cubic spline analysis of mBMI and the OR for postoperative pulmonary infection.

  Fig. 3. Subgroup Analysis of mBMI and In-Hospital Mortality Risk. (A) Subgroup analysis of mBMI and the risk of in-hospital mortality. (B) Subgroup analysis of ln(mBMI) and the risk of in-hospital mortality. Subgroups include gender, age, history of ischemic stroke, history of atrial fibrillation, carotid artery stenosis, valvular disease, preoperative eGFR < 90, preoperative serum creatinine > 100, history of myocardial infarction, ASA score, use of left internal mammary artery graft, and the number of target vessels.

(A) Sex subgroup; (B) Age subgroup; (C) eGFR subgroup; (D) Creatinine subgroup; (E) ASA score subgroup; (F) Valvular disease subgroup; (G) History of ischemic stroke subgroup; (H) Carotid stenosis subgroup.
