From: Risk factors and mortality of patients undergoing hip fracture surgery: a one-year follow-up study
Time to death from surgery adjusted to delayed surgery (panel A) and Lee score (panel B). Lee score < 2: hazard ratio = 0.278; CI 95% = 0.128–0.606; P value = 0.001 Surgery discharge < 48 hours from hospital admission: hazard ratio = 0.640; CI 95% = 0.389–0.894; P value = 0.045.
