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

purposeThis study aimed to clarify the relationship between diurnal awake bruxism (AB) awareness, tooth-contacting habit (TCH) awareness, and the electromyographic (EMG) waveform integral value. MATERIALS AND

methodsUnilateral masseteric EMG recordings during the daytime were performed on the habitual masticatory side using an ultraminiature wearable EMG device. One hundred and seven participants (50 and 57 with and without diurnal tooth clenching (d-TC) awareness, respectively) were included. d-TC awareness and TCH awareness were assessed using questionnaires. The standardized burst integral (S-integral) value was calculated for each participant.

resultsThere was a statistically significant association between d-TC awareness and TCH awareness. The S-integral values were not significantly associated with the awareness d-TC or TCH. The frequency distribution of EMG waveforms of the awareness and non-awareness groups exhibited wide-range overlaps both for d-TC and TCH.

conclusiond-TC or TCH awareness showed no clear correlation with the S-integral value, suggesting that it is important to evaluate AB and TCH based on objective and quantitative test results, such as the masseter muscle's EMG data. CLINICAL RELEVANCE: Diagnosis, treatment, and management of AB and TCH are important issues in dental medicine. The obtained results regarding the actual state of awareness of AB and TCH, and the EMG integral value that was one of the important EMG indices, were considered useful information for establishing diagnostic and assessment methods for AB and TCH in future clinical dentistry.
