ALB and hip fracture: To illustrate, Zhao et al. conducted a retrospective study on 1515 elderly hip fracture patients and reported that low albumin levels (< 35 g/L) (OR = 1.52, p = 0.04) and D-dimer levels > 1.59 mg/L (OR = 2.19, p < 0.001) were independently correlated with preoperative DVT [20].
