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

Temporomandibular disorders (TMDs) are the second most common reason for orofacial pain with myalgia being the most prevalent diagnosis. Overuse of the masticatory muscles and the presence of stress are both risk factors for myalgia. The extent to which these risk factors interact remains unclear, including whether psychological stress contributes to increased masticatory muscle activity. The purpose of this scoping review was to identify, examine, and map the available literature exploring the relationship between psychological stress and masticatory muscle electromyography (EMG). Pre-clinical and clinical studies that studied adults with or without TMD who were exposed to psychological stress and had masticatory muscle electromyography recordings were included. The electronic databases CINAHL, EMBASE, Medline, and PsycINFO were searched in March 2025. Using a pre-defined data extraction sheet, basic study information and specific results regarding the research question were extracted. These were analysed and the results were described based on the type of study (pre-clinical
