The independent risk factors included lower albumin level (OR 1.20; 95% CI 1.07–1.36; P = 0.003), hypertension (OR 3.32; 95% CI 1.41–7.79; P = 0.006), extended time to imaging for DVT detection (OR 1.14; 95% CI 1.06–1.22) and diagnosis of intertrochanteric fracture over femoral neck fracture (OR 3.75; 95% CI 1.42–9.88). This evidence concerns the gene ALB and deep vein thrombosis.
