The table shows baseline features for the whole cohort, patients with a proximal femur fracture and patients with a fall without fracture. The parameters are grouped for patients’ demographic characteristics, the prefall function and health status, treatment quality, baseline laboratory parameters, and nutrition status. The last column shows the -value for the difference between the fracture group and the fall group. BMI: body mass index. ASA: American Society of Anesthesiologists Score. STS: “sit-to-stand” index. : number of participants in analysis. SD: standard deviation. Indicates statistical significance.
