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
introductionThe increasing number of geriatric traumatology cases has intensified the need to reliably and objectively evaluate local bone quality, the latter poses a decisive factor for the choice of an optimal approach to treat osteoporotic fractures. Osteodensitometry imaging techniques are not routinely available in acute operative settings, nor do they provide objective information on local bone properties specifically needed for the prognosis of implant stability. MATERIALS AND
methodsThis study sought to verify ex vivo the feasibility and sensitivity of a novel method for the determination of local bone strength in the acute operative setting (intraoperative osseomechanical strength measurement; IOSM) that is based on the principle of material displacement resistance against the force of a rotary indenter. Samples consisted of human femoral heads obtained after total hip replacement. Comparisons were made with results obtained via conventional dual-energy X-ray absorptiometry (DXA) and quantitative computed tomography (qCT).
resultsRegression analyses of the results showed a highly significant correlation between the IOSM and the control methods (r = 0.61 and r = 0.56; p < 0.01), indicating that this new approach qualifies as a reliable tool for the intraoperative evaluation of the intrinsic local bone strength.
conclusionsThe intraoperative integration of this method may support surgeon on taking proper decisions in terms of optimal surgical approaches and prevention of complications inherent to osteoporotic bone.
