Sarcopenia in atrial fibrillation: a prospective study.
Article in Turkish journal of medical sciences, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Background/aim: The link between atrial fibrillation (AF) and lean body mass is unclear. This study presents the effects of AF on sarcopenia indices, including ultrasonographic muscle architecture. Materials and methods: In this study conducted in neurology units, 72 subjects with AF (mean age: 71 ± 11years, 49% female) were compared with 538 without AF (mean age:66±12years; 53% female) in terms of sarcopenia indices [anthropometry; Short Physical Performance Battery (SPPB); hand grip strength (HGS); bioimpedance analysis (BIA) indices; skeletal muscle mass index (SMMI) normalized to weight, height and body mass index (BMI); and phase angle (PhA)]; muscle ultrasonography [thickness, cross-section area (CSA), fiber length (fL) and pennation angle (PeA) of rectus femoris (RF), biceps brachii (BB), vastus lateralis (VL), vastus intermedius (VIM) and gastrocnemius medialis (GCM)]; possible causes of sarcopenia such as malnutrition; and consequences of sarcopenia [fall, fatigue, SarQol] along with sarcopenia screening (SARC-F). Possible associations were tested in multiple exploratory linear models, and partial r(pr) and p were reported. Results: Participants with AF exhibited significantly higher SARC-F and SarQol scores. In multivariable models adjusted for age, sex, height, and body weight, AF was independently linked to lower mean and maximum HGS (pr = -0.137, p = 0.014; pr = -0.130, p = 0.02), reduced PhA (pr = -0.193, p < 0.001), decreased RF thickness (pr = -0.120; p = 0.004), and diminished RF+VIM thickness (pr = -0.098; p = 0.019). Additional muscle ultrasound parameters, including BB-CSA, RF-CSA, BB-brachialis thickness, VL fL, and PeA and BIA indices, including SMMI(height), SMMI(weight), and SMMI(BMI), tended to be lower in AF. Conclusion: AF is linked to impaired muscle health and reduced quality of life. Management should include thigh muscle ultrasound and strategies to prevent malnutrition.
