Searches were conducted in OVID Medline, OVID Embase, CINAHL, PsycINFO, the Cochrane Library and SCOPUS. Randomised controlled trials were included if they evaluated the impact of decision aids as defined by the International Patient Decision Aids Standards Collaboration. Where possible, meta-analysis was undertaken. Where meta-analysis was not possible, we conducted a narrative synthesis. Risk of bias in included trials was assessed using the Cochrane Collaboration's risk of bias tool. Data were analysed using STATA. Five RCTs were identified that evaluated the effectiveness of decision aids in the context of vaccination decision making. Meta-analysis of four studies showed that decision aids may have slightly increased vaccination uptake, but this was reduced to no effect once stud of the effectiveness of different elements and formats. Standardising decision aids would also allow for easier comparison between decision aids.This study aims to investigate the feasibility of quantitative ultrasonic backscatter in evaluating human cortical and trabecular bone densities in vivo based on a head-down-tilt bed rest study, with 36 participants tested through 90 d of bed rest and 180 d of recovery. Backscatter measurements were performed using an ultrasonic backscatter bone diagnostic instrument. Backscatter parameters were calculated with a dynamic signal-of-interest method, which was proposed to ensure the same ultrasonic interrogated volume in cortical and trabecular bones. The backscatter parameters exhibited significant correlations with site-matched bone densities provided by high-resolution peripheral quantitative computed tomography (0.33 less then |R| less then 0.72, p
