Metabolic and Fluid Biomarkers Support Microglia Activation in Amyotrophic Lateral Sclerosis.
Article in Annals of clinical and translational neurology, 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
Amyotrophic lateral sclerosis is an incurable neurodegenerative disease involving motor neuron degeneration and metabolic and immune dysfunction. We combined clinical data, cerebrospinal fluid biomarkers and fluorodeoxyglucose positron emission tomography with magnetic resonance imaging to investigate the role of reactive microglia in disease pathogenesis. Patients showed increased cerebrospinal fluid levels of neurofilament light chain and chitinases, along with hypermetabolism in the medulla oblongata. Chitinase levels correlated with brainstem metabolism and clinical severity. These findings suggest a link between microglial activation, brainstem hypermetabolism and disease progression in amyotrophic lateral sclerosis, supporting a central role for neuroinflammation in disease pathogenesis.
