What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
unlabelledThe fracture predictive value of quantitative ultrasound (QUS) may be modified by previous fracture status. Non-significant associations between QUS parameters and fracture risk were observed among frail older people with a history of fracture. These findings suggest that QUS measurements for frail older people might be more useful in those without a fracture history.
introductionQuantitative ultrasound has been shown to predict risk of fracture in various populations. However, this ability may be modified by the presence of previous fracture in very frail older people.
methodsWe assessed bone strength by QUS and clinical risk factors at baseline for 1,982 institutionalised older people. Fractures were ascertained for 2 years from baseline and validated by X-ray reports.
resultsStudy participants were very old (mean age = 85.7 +/- 7.1 years) and frail (70% using walking aids). Forty-five percent reported a history of fracture. During a mean follow-up period of 1.64 years, 335 participants suffered a fracture or fractures. Fracture rates were significantly higher in participants with a history of fracture compared with those without a history of fracture (16.0 vs 9.2 per 100 person years, p < 0.001). Significant associations between fracture risk and QUS parameters (broadband ultrasound attenuation and velocity of sound) were observed among participants without a history of fracture (both p < 0.01), but not among those who had a fracture history (both p >/= 0.7).
conclusionsIn very frail older people, QUS measurements may be more useful for assessing fracture risk in those without a history of fracture after age 50.
