Design and Validation of an Instrument to Assess Awake Bruxism in Adults.

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
The definition of bruxism has evolved over the past few years. Currently, two clinical presentations are recognized: Sleep Bruxism (SB) and Awake Bruxism (AB). Although various bruxism assessment strategies have been developed to guide clinical practice, no specific, valid, reliable tool has been designed specifically for patients with AB.
aimTo design and validate a questionnaire to assess the presence, severity and symptomatology of AB. Secondary objectives included exploring the clinical and psychiatric manifestations of AB. MATERIALS AND
methodA prospective case-control study was conducted on 14 AB cases and 20 healthy controls. The presence or absence of the condition was confirmed by electromyographic study. A specific questionnaire for AB (AB-Q) was developed, and AB psychometric properties were evaluated. The AB-Q consists of 24 items grouped into four domains. The reliability, sensitivity and specificity of the AB-Q were assessed.
resultsSignificant differences were observed between groups: EMG-confirmed bruxism episodes were recorded in all 14 AB patients and none of the controls. The AB-Q showed high internal consistency (Cronbach's alpha: 0.924) and strong discriminative capacity, with a sensitivity of 100% and a specificity of 90%. A significant association was found between bruxism and the presence of anxiety and depressive disorders, as well as obsessivecompulsive traits.
conclusionThe AB-Q questionnaire proved to be a useful tool with acceptable clinimetric properties for assessing the presence and severity of bruxism.
