Changes in body composition and phase angle from diagnosis to gastrostomy, in motor neuron disease patients: a longitudinal study.
Article in European journal of clinical nutrition, 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
Limited studies have explored the longitudinal alterations of fat-free mass (FFM), fat mass (FM), and phase angle (PhA) in the motor neuron disease (MND) population. This pilot longitudinal study investigated body composition changes via bioimpedance analysis (BIA) at time of diagnosis and gastrostomy. Nineteen patients (n = 11, 57.9% females) were included. Statistically significant reductions in FFM [median (IQR) 43.0 (17.8) kg to 42.1 (16.7) kg, p < 0.001] and PhA [4.6 (2.0)° to 4.5 (2.1)°, p = 0.012] were found. FFM (p = 0.007, 95% CI 0.505, 1.32) and FM (p = 0.024, 95% CI 0.160, 1.249) were significant predictors of weight change, with FFM accounting for 72% of the change. Larger longitudinal studies are needed to explore the clinical benefit associated with reducing pre-gastrostomy FFM loss in the MND population. In the interim, clinicians should consider monitoring body composition and implementing interventions aimed at preserving body weight and composition, particularly FFM, prior to gastrostomy placement.
