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

Ocular neuropathic pain is typically treated with local anti-inflammatory and neuroregenerative agents, and psychological approaches such as cognitive behavioral treatment, as well as systemic pharmacological medications and nerve blocks. In recalcitrant cases, neurostimulation or neuromodulation may be considered. In this review, we evaluate the existing literature for the use of non-invasive forms of neurostimulation: home-based extra nasal neurostimulation (iTear100), extracranial direct current stimulation (tDCs), transcutaneous electrical nerve stimulation (TENs) and transcranial magnetic stimulation therapy (TMS). We compared the mechanism of action of these therapies and clinical studies of their effectiveness. Although most of the published literature is based on general neuropathic pain and often combinatorial treatment, we compared the pros and cons of using such modalities for ocular neuropathic pain, including effectiveness, potential side effects, convenience and other factors.
