Bright tongue sign as a radiological clue of bulbar onset amyotrophic lateral sclerosis: A case report.

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
Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease characterized by degeneration of motor neurons, with the tongue often involved in clinical presentation. In this case, a 60-year-old female presented with progressive choking episodes and speech slurring over 9 months, exhibiting dysarthria, prominent tongue atrophy, fasciculations, and hyperreflexia. Needle electromyography (EMG) showed diffuse chronic neurogenic changes with signs of active denervation changes prominent on the tongue and right arm with normal sensory nerve studies. Magnetic resonance imaging (MRI) brain imaging revealed a Diffuse T1 Weighted image (T1WI) hyperintense of tongue known as "bright tongue sign" indicating fatty infiltration of tongue muscles, consistent with neurogenic atrophy. This case underscores the importance of recognizing this characteristic tongue hyperintensity as a valuable radiological clue in diagnosing bulbar-onset ALS and highlights the potential for early diagnosis to improve patient management and outcomes.
