Survival curves for mortality for patients in the orthopedic (solid line) and geriatric (dotted line) cohorts. The orthopedic cohort (n = 131) was treated in an orthopedic department without geriatric cooperation. The geriatric cohort (n = 203) was treated in a dedicated Unit for PostOperative Geriatric care. Survival is adjusted for age, sex, and Cumulative Illness Rating Scale calculated with a Cox regression analysis. P values refer to log-rank test. Reproduced, with permission, from Boddaert et al.
