Fig. 4From: Development and validation of a nomogram for blood transfusion during intracranial aneurysm clamping surgery: a retrospective analysisNomogram to predict the probability of intraoperative blood transfusion in the patients who underwent intracranial aneurysm surgery. For example, a female patient with a ruptured aneurysm, D-dimer (8 mg/L), WBC (10 × 1012), PLT (150 × 109), and HB (100 g/L), had a total score of 342 in terms of these variables and a predicted probability of intraoperative blood transfusion of 85.8%. WBC, White blood cell; HB, Hemoglobin; PLT, PlateletBack to article page
