To identify potential parameters associated with the incidence of AL, serum albumin (normal range: 3.5–5.0 g/dl), serum creatinine (normal range: 0.7–1.3 mg/dl), international normalized ratio (INR), and activated partial thromboplastin time (aPTT; normal range: 26–37 s) were assessed before surgery, at POD 0 after surgery and on POD 1. The gene discussed is ALB; the disease is axial length measurement.
