A review of descending pain modulation in humans.
Review in Frontiers in pain research (Lausanne, Switzerland), 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
Descending pain regulation has been widely studied in animals and recent studies in humans have offered new insights into this complex mechanism. This review paper aims to investigate this process in humans to better understand how pain is modulated in the body. This review included primary articles from PubMed related to pain modulation in the human brain or spinal cord. Book chapters, sources using animal models, and review papers were excluded from the paper. Findings consistently noted the periaqueductal grey and rostral medulla as central hubs of descending pain modulation, while cortical regions including the prefrontal cortex, anterior cingulate cortex, insula, and amygdala exhibited variable and context-dependent contributions. Cognitive and emotional processes, including distraction, imagery, music, catastrophizing, and anxiety, were found to modulate descending pain pathways via altered connectivity between cortical and brainstem regions. Studies also identified therapeutic applications, with transcranial direct current stimulation and spinal cord stimulation demonstrating effects on descending modulatory circuits. These studies identify exciting new progress in our understanding of pain modulation whilst also highlighting a need for further study in human populations to clarify certain inferences.
