Biological Markers of Brain Network Connectivity and Pain Sensitivity Distinguish Low Coping from High Coping Veterans with Persistent Post-Traumatic Headache.
Observational study in Journal of neurotrauma, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Headache is the most common pain complaint following mild traumatic brain injury. Roughly half of those with persistent post-traumatic headache (PPTH) also report neck pain, which is associated with greater severity and functional impact of headache. This observational cohort study aimed to identify biological phenotypes to help inform mechanism-based approaches in the management of PPTH with co-occurring neck pain. Thirty-three military veterans [mean (standard deviation) = 37 ± 16 years, 29 males] with PPTH completed a clinical assessment, quantitative sensory testing, and magnetic resonance imaging of the brain and cervical spine. Multidimensional phenotyping was performed using a Random Forest analysis and Partitioning Around Medoids clustering of input features from three biological domains: (1) resting state functional connectivity (rsFC) of the periaqueductal gray (PAG), (2) quality and size of cervical muscles, and (3) mechanical pain sensitivity and modulation. Two subgroups were distinguished by biological features that included forehead pressure pain threshold and rsFC between the PAG and selected nodes within the default mode, salience, and sensorimotor networks. Compared to the High Pain Coping group, the Low Pain Coping group exhibited higher pain-related anxiety (
