OBJECTIVE: Incidental aneurysms pose a challenge for physicians, who need to weigh the rupture risk against the risks associated with treatment and its complications. A statistical model could potentially support such treatment decisions. A recently developed aneurysm rupture probability model performed well in the US data used for model training and in data from two European cohorts for external validation. Because Japanese and Finnish patients are known to have a higher aneurysm rupture risk, the authors' goals in the present study were to evaluate this model using data from Japanese and Finnish patients and to compare it with new models …

Purpose: The purpose of this study is to quantify the effect of residential modification on decreasing the risk of physical function decline in 2 years.

Design: Cohort study using propensity scores method to control for baseline differences between individuals with residential modifications and those without residential modifications.

Participants: Participants (N = 9,447) were from the Second Longitudinal Study on Aging, a nationally representative sample of the civilian noninstitutionalized population, aged 70 years and older in the United States at the time of baseline interview in 1994-1995.

Methods: Participants self-reported residential modifications at baseline (e.g., railings, bathroom modifications). The decline in …
