Super elderly patients with intertrochanteric fractures do not predict worse outcomes and higher mortality than elderly patients: a propensity score matched analysis

Figure 2. Kaplan-Meier survival curves for elderly and super elderly patients after hip surgery. Patients older than 90 years had a risk of death at 1 year that was 0.98 time as high, a risk of death at 2 years that was 1.6 times as high, a risk of death at 3 years that was 1.5 times as high and a risk of death at 4 years that was 1.3 times as high as the risk compared with the patients less than 90 years. However, the Kaplan-Meier survival curve showed no significant difference between the two groups of patients on cumulative survival rate. (p=0.081, log-rank).
