1 · What the graph read from it

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.

2 · The registry

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

Objectives: This study aimed to evaluate phase angle (PhA) as a clinical marker of sarcopenia within the multidimensional Structure-Quality-Strength-Mobility (SQSM) framework and to compare its associations with muscle strength and physical performance against sarcopenia defined by appendicular skeletal muscle mass index (ASMI). Methods: A cross-sectional study was conducted on 87 older adults (mean age 68.8 years; 70.1% female) recruited into a structured exercise program. PhA and ASMI were measured via bioelectrical impedance analysis in the program's final week. Muscle strength and physical performance were measured using the Asian Working Group for Sarcopenia definitions. The SQSM-operationalised definition(OD) of sarcopenia was classified as low PhA combined with either low handgrip strength (HGS) or gait speed(GS). Logistic regression assessed associations. Results: Phase angle ≤4.25° was associated with low HGS (OR = 2.51, p = 0.058), GS (OR = 3.96, p = 0.010), and falls (OR = 4.20, p = 0.024). SQSM-OD of sarcopenia showed higher prevalence and stronger association with falls (OR = 5.77, p = 0.008) than ASMI-defined sarcopenia. Conclusion: PhA was associated with low muscle strength, gait speed and falls supporting its role as a marker of muscle quality. SQSM-OD identified more at-risk individuals highlighting the utility of incorporating muscle quality into sarcopenia assessment.
