Figure 1.

Three representative patients with an intertrochanteric fracture to show the changes of S100B during admission calculated with values of the mixed model analysis of all samples. The final model included delirious state (p < 0.001), day of blood withdrawal (p < 0.001), pre- or postoperative status (p = 0.001) and type of fracture (p = 0.036). Postoperative day 0 is day of surgery.
