From: Who benefits from orthogeriatric treatment? Results from the Trondheim hip-fracture trial
Results of mixed model analysis: Estimated outcome in each subgroup and treatment, with 95 % confidence interval. P-values are reported for interaction between subgroup and treatment. For example, p = 0.004 for age and NEAS at 4 months: The treatment effect (difference in NEAS) for patients aged < 80 is significantly larger than the difference for patients aged ≥ 80
