1 · What the graph read from it

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.

2 · The registry

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

backgroundPersistent post-traumatic headache (PTH) and migraine frequently present with photic hypersensitivity that exacerbates headache symptoms. We sought to determine whether persistent PTH is associated with altered brain responses to visual stimuli and to explore shared neural mechanisms of photophobia with migraine.

methodsThis cross-sectional functional magnetic resonance imaging (fMRI) study included 80 adults with persistent PTH, 261 with migraine, and 143 healthy controls (HCs). All participants underwent visual stimulation using a flickering checkerboard during a 3T fMRI session. Blood oxygen level-dependent (BOLD) responses were examined using whole-brain and region-of-interest (ROI) analyses. All analyses were adjusted for age and sex.

resultsWhole-brain analysis revealed no significant BOLD differences across the full persistent PTH, migraine, and HC groups. However, participants with persistent PTH who experienced photophobia during the scan (n = 41) showed greater activation in the anterior and midcingulate cortex compared with HCs (P

conclusionsPhotophobia in persistent PTH is associated with greater activation in cortical regions implicated in pain processing. These patterns parallel those observed during migraine attacks, indicating shared neural mechanisms between the two headache disorders.
