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

The pathway that underlies exacerbation of migraine headache by light has not been elucidated in the human brain but has recently been reported in a rodent model. We employ diffusion weighted imaging and probabilistic tractography to map connectivity of direct pathways from the optic nerve to the pulvinar implicated with whole-body allodynia during migraine. Nine healthy subjects were recruited to the study and underwent scanning on a 3T magnet. We were able to define well-known image-forming (optic nerve -> lateral geniculate -> visual cortex) as well as a less known nonimage forming visual pathway from the optic chiasm to the pulvinar, and from the pulvinar to several associative cortical brain regions. Such pathway may allow photic signals to converge on a thalamic region we described recently to be selectively activated during migraine headache. Consistent with physiological and anatomical studies in rats, the data provide an anatomical substrate for exacerbation of migraine headache by light in the human.
