A nomogram for assisting in diagnosing mouth breathing based on maxillofacial surface electromyographic activity.
Article in BMC oral health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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.
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
objectiveA nomogram based on maxillofacial surface electromyographic (sEMG) activities was developed to assist in diagnosing mouth breathing (MB).
methodsDifferences in maxillofacial sEMG activities between MB and nasal breathing (NB) subjects were compared across a sample of 250 participants to identify MB diagnostic factors, a nomogram was developed to assist in diagnosing MB.
resultsIn the univariate analysis, there were significant differences in sEMG activity of masseter muscle with the lips closed lightly, orbicularis oris superior during rest, orbicularis oris superior with the lips closed lightly (OOS3), orbicularis oris superior during swallowing, mentalis muscle during rest, mentalis muscle during maximal intercuspation (MT2), mentalis muscle with the lips closed lightly (MT3) and mentalis muscle during swallowing between the MB and NB groups. Multivariate analysis revealed that OOS3 and MT3 were independent risk factors for MB, while MT2 might be a protective factor against MB. The nomogram exhibited a good clinical application value with an area under the ROC curve of 0.774 (95% CI 0.713-0.834) and fitted calibration curves.
conclusionMB could affect maxillofacial sEMG activities. We developed a nomogram to assist in diagnosing MB in the clinic. CLINICAL SIGNIFICANCE: The nomogram can help clinicians diagnose MB quickly and easily, providing a more effective way to diagnose children with MB early so that they can receive timely treatment and block abnormal neuromuscular reflexes early, thereby avoiding the harmful effects of MB.
