Multicenter Study
A selection strategy was developed for fracture reduction programs in frail older people.
The aims of this study were to develop and evaluate a simple index for assessing the risk of fractures after a fall and to propose a selection strategy for identifying elderly individuals at high risk of both falls and fall-related fractures. ⋯ The index could help rationalize fracture prevention programs for frail older people.

To examine whether the prestige of a journal, measured by its impact factor, influences the numbers of citations obtained by published articles, independently of their scientific merit. ⋯ The prominence of the journal where an article is published, measured by its impact factor, influences the number of citations that the article will gather over time. Citation counts are not purely a reflection of scientific merit.

To determine the measurement properties of an Italian Version of the Lower Extremity Functional Scale (LEFS) in patients with lower extremity musculoskeletal dysfunction. ⋯ The Italian version of the LEFS is a valid, reliable, and responsive tool that can be used to measure function in Italian patients with lower extremity musculoskeletal dysfunction.

To compare three ad hoc methods to estimate the marginal hazard of incident cancer acquired immune deficiency syndrome (AIDS) in a highly active antiretroviral therapy (1996-2006) relative to a monotherapy/combination therapy (1990-1996) calendar period, accounting for other AIDS events and deaths as competing risks. ⋯ When competing risks are independent of the event of interest, only method 1 produced unbiased estimates of the marginal HR, although independence cannot be verified from the data. When competing risks are dependent, method 1 generally produced the least-biased estimates of the marginal HR for the scenarios explored; however, alternative methods may be preferred.
