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

This systematic review aims to assess the impact of rapid maxillary expansion (RME) on masticatory muscle activity through electromyographic analysis. A systematic review was conducted according to the Cochrane Collaboration guide. The PICO strategy was employed to formulate the clinical question. A comprehensive search review was performed up to September 2022 across five databases (PubMed, Web of Science, Scopus, Embase, and Cochrane) and gray literature (Google Scholar). The risk of bias was performed using the Risk of Bias in Nonrandomized Studies of Interventions (ROBINS I) tool. Means and standard deviations were extracted to perform the meta-analysis, and overall quality was assessed using the Grading of Recommendations Assessment, Development, and Evaluation approach. Nine nonrandomized studies with a moderate risk of bias were included in this systematic review. Meta-analysis of electromyographic data during clenching demonstrated an increase in anterior temporal muscle activity after RME (
