Integrated rehabilitation and ambulatory recovery in older adults with hip fracture according to muscle strength and sarcopenia status: a secondary analysis of a randomized controlled trial.

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
purposeSarcopenia and impaired muscle strength are common in older adults with hip fractures and are strongly associated with poor functional recovery. Although integrated multidisciplinary rehabilitation improves outcomes after hip fracture, whether its benefits differ according to baseline muscle strength or sarcopenia severity remains unclear. This study aimed to examine whether the functional benefits of Fragility Fracture Integrated Rehabilitation Management (FIRM) vary according to sarcopenia status and handgrip strength (HGS) in older adults after hip fracture surgery.
methodsThis was a secondary analysis of a multicenter randomized controlled trial comparing FIRM with conventional rehabilitation in adults aged ≥ 65 years undergoing hip fracture surgery. The primary outcome was independent ambulation at 12 months. Sarcopenia was classified using three approaches: sarcopenia versus non-sarcopenia, a three-level classification (non-sarcopenia, possible sarcopenia, and sarcopenia), and low versus normal HGS. Logistic regression models, including treatment, sarcopenia status, and their interactions, were fitted with sequential adjustments for relevant covariates.
resultsOf the 203 randomized participants, 119 (58.6%) completed the 12-month follow-up. Treatment-by-sarcopenia interactions were not statistically significant. Stratum-specific analyses suggested a pattern of greater functional improvement with FIRM than with conventional rehabilitation, particularly among participants with low HGS and, to a lesser extent, those with sarcopenia. In the fully adjusted models, FIRM was associated with greater improvement in independent ambulation among participants with low HGS (odds ratio, 4.25; risk difference, + 34.7%; P = 0.014).
conclusionsIntegrated rehabilitation may provide greater functional benefits than conventional rehabilitation in older adults with hip fractures, particularly among those with low muscle strength. However, given the lack of statistically significant interaction effects and the attenuation of the observed associations in the fully adjusted models, these findings should be interpreted as exploratory.
