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
<p>Introduction: Physical frailty in older adults is frequently associated with adverse outcomes, yet most assessment tools rely on subjective or time-consuming measures. This study explores ultrasound-derived anterior thigh muscle thickness (ATMT) as an objective marker for frailty.
methodsThis cross-sectional study included 641 patients aged 65 years and older. Comprehensive geriatric evaluations and ATMT measurements by ultrasound were performed. Frailty was diagnosed using the fried frailty phenotype. The association between ATMT and frailty was examined using multivariate logistic regression analysis.
resultsParticipants' mean age was 75 ± 6.4 years; 62.9% were women, and 12% were frail. Frail individuals had significantly lower ATMT compared to non-frail counterparts (p < 0.001). ATMT remained independently associated with frailty after adjusting for confounders (β = 0.94, 95% confidence interval [CI]: 0.90-0.99, p = 0.033). The area under the receiver operating characteristic curve for ATMT predicting frailty was 0.660 (95% CI: 0.62-0.69; p < 0.001). Sex-stratified analyses revealed higher accuracy in men (AUC = 0.757) than in women (AUC = 0.599). The optimal ATMT cut-off was ≤30.5 mm, with a negative predictive value of 90.3%.
conclusionsUltrasound-derived ATMT offers a simple, radiation-free, and objective method for frailty screening, showing stronger discriminative ability in men and moderate accuracy in women. It may be used as a practical screening measure in combination with other geriatric assessment tools in outpatient settings. </p>.
