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

backgroundClinical observations have shown that transcutaneous occipital nerve stimulation (tONS) is effective in treating migraine. However, the underlying mechanisms are poorly understood. This study employs a rodent model to investigate the therapeutic effects of tONS on migraine-related pain and to explore potential mechanisms.

methodsThe SD rats were used to establish the migraine model by repeated epidural infusions of inflammatory soup (IS). Modified bilateral electrodes were attached noninvasively for tONS treatments. Periorbital mechanical thresholds were assessed using von-Frey filaments, and other pain-related nociceptive behaviors were analyzed through video recordings. The expressions of c-Fos, synaptophysin (Syp) and calcitonin gene-related peptide (CGRP) in the trigeminal nucleus caudalis (TNC) and/or periaqueductal gray (PAG) area were measured by immunofluorescence and western blotting analyses. The excitatory synaptic transmission in the PAG was detected by whole-cell patch-clamp recording among migraine rats.

resultsThe reduction in periorbital mechanical thresholds induced by repeated IS infusions was partially reversed by tONS treatments in migraine rats. Other pain-related behaviors, including exploration, rest, and unilateral grooming, consistently improved following tONS treatment. The TNC and PAG area were activated after IS modeling, and the CGRP expressions in the PAG significantly decreased after tONS treatments. tONS could inhibit the enhanced excitatory synaptic transmission in the PAG of migraine rats.

conclusionsOur findings suggest that tONS has therapeutic potential in treating migraine, with the PAG excitability and CGRP expression playing a role in its mechanisms of action. tONS may represent a promising non-invasive neuromodulation approach for the management of migraine in the future.
