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
INTRODUCTION AND
aimAccurate determination of walking independence in older adults after hip fracture surgery is crucial for selecting appropriate walking strategies and providing fall prevention guidance. We developed and validated a clinical prediction rule (CPR) to determine level-surface walking independence and community walking independence in older adults with hip fractures.
methodsIn a multicenter, cross-sectional study, we investigated 289 older inpatients with hip fractures. A backward stepwise logistic regression analysis was performed to develop a CPR for determining level-surface walking independence and community walking independence. The independent variables incorporated the patients' walking and balance evaluations at discharge, including the Berg Balance Scale (BBS), the Timed Up and Go (TUG) test, and maximum walking speed (MWS), as well as age and cognitive function evaluations. We used a bootstrap internal validation for the CPR's internal validation.
resultsAt their hospital discharge, 171 patients had achieved level-surface walking independence, and 51 had achieved community walking independence. As the level of walking independence decreased, patients tended to be older, with lower BBS scores and slower TUG times and walking speeds. As diagnostic factors, the level-surface walking model included age, BBS, and cognitive decline; the community walking model included BBS, TUG, and MWS. The diagnostic accuracy, represented by the area under the curve (confidence interval), was 0.88 (0.84-0.92) for the level-surface walking model and 0.81 (0.74-0.87) for the community walking model. Internal validation confirmed that the models' discrimination accuracy was good, and no model overfitting was observed.
conclusionsWe developed a moderately accurate CPR to determine walking independence in hip fracture patients. CPR can be a useful indicator for determining an individual's walking independence at present, but external validations with other samples are necessary.
