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
Mechanical vibration devices such as AcceleDent have been marketed as non-invasive adjuncts capable of accelerating orthodontic tooth movement. The proposed mechanism involves the stimulation of cellular activity and bone remodeling. The aim of this study was to determine whether the use of AcceleDent, in combination with clear aligner therapy, produces a measurable increase in the surface temperature of intraoral tissues. Twenty-two adult patients (mean age: 39 ± 15 years) undergoing orthodontic treatment with clear aligners (Invisalign) participated in this crossover study. Infrared thermography (A35, FLIR, Wilsonville, USA) was used to record temperature measurements of gingival and dental surfaces. Each participant underwent two experimental conditions on separate days: (1) wearing the AcceleDent device while active (vibrating) and (2) wearing the same device inactive (non-vibrating). After a 20-minute thermal acclimatization period, the device was applied for 20 min before imaging. No statistically significant differences were observed in surface temperature between the vibrating and non-vibrating conditions (Gingiva: p = 0.69; Tooth: p = 0.76). Likewise, no significant differences were detected at baseline between the two sessions (Gingiva: p = 0.35; Tooth: p = 0.57). The use of AcceleDent vibration during clear aligner therapy does not result in an increase in the surface temperature of gingival or dental tissues, as measured by infrared thermography. This study provides evidence that AcceleDent vibration does not produce thermal changes in intraoral tissues, suggesting it is thermally safe for use alongside clear aligners. Infrared thermography may serve as a non-invasive tool to monitor physiological effects of orthodontic devices.
