Lingual pressure as a physiological indicator for dysphagia in amyotrophic lateral sclerosis and multiple system atrophy.
Article in Neurodegenerative disease management, 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
backgroundThis study aimed to characterize lingual pressure (LP) and clarify its association with dysphagia in patients with amyotrophic lateral sclerosis (ALS) and multiple system atrophy (MSA).
methodsWe examined 52 patients with ALS (Spinal-onset, 39; bulbar-onset, 13) and 36 patients with MSA (MSA-C, 26; MSA-P, 10). LP was measured using a balloon-type instrument during isometric contractions. Maximum LP (MLP) and 80% endurance of LP (ELP; duration above 80% of MLP during 7 seconds) were analyzed against videofluoroscopic findings of dysphagia.
resultsBoth parameters significantly correlated with food intake scales, especially in ALS. Liquid aspiration was predicted in ALS with 80.8% accuracy (AUC = 0.794,
conclusionLP thus may represent a physiological indicator for dysphagia detection and management.
