Older patients with less skeletal muscle mass gain more skeletal muscle in rehabilitation wards after fractures.

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
backgroundWe hypothesized that old patients could increase skeletal muscle mass after fractures by exercise rehabilitation, even if they have a low initial muscle mass.
aimThis study aimed to evaluate the relationship between skeletal muscle mass and skeletal muscle changes in older patients after fractures.
methodsThis case-control study took place in rehabilitation wards and included 807 patients aged ≥ 65 years with fractures. Patients were divided into two groups based on the skeletal muscle index (SMI) on admission by the sarcopenia cut-off points: low SMI group included patients with SMI < 7.0 for men and < 5.7 for women and high SMI group included patients with SMI ≥ 7.0 for men and ≥ 5.7 for women. Analysis of comparison between the two groups and multivariate logistic regression analyses were performed.
resultsThe SMI gain was significantly higher in the low SMI group (0.20) than in the high SMI group (0.00, p < 0.001). There were also the differences in age, BMI, mini nutritional assessment short form, Charlson comorbidity index, length of hospital stay, and protein intake. The SMI on admission was significantly associated with increased SMI after rehabilitation (odds ratio 0.569, 95% confidence interval 0.455‒0.710). Length from onset to transfer to the hospital, hospital stay, and period of exercise therapy were also significantly associated with increased SMI.
conclusionsWe found that older patients with low SMI after fracture gained more skeletal muscle mass than those with high SMI following exercise rehabilitation. In addition, SMI on admission was one of the factors independently associated with increased SMI.
