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

objectivesNew solutions for the dynamic assessment of the moving structures of the temporomandibular joint (TMJ), such as the intra-articular disc and the head of the mandible, are required for magnetic resonance imaging (MRI). Therefore, we propose a simple, graded bite block for dynamic MRI examination of the TMJ.

methodsThe bite block consists of three main functional elements: a groove for the biting edges of the upper incisors, steps with bite surfaces for the biting edges of the lower incisors and a handle for easy placement and control of the device. The block is easily manufactured using commercially available 3D printers. The closed-mouth part of the study was performed without the bite block. The patient was instructed to place the central incisors' biting edges in the upper groove. The lower incisors' biting edges were placed consecutively on the first step, second step, and so on, in increasing order, until maximal opening was reached.

resultsNinety-five MR examinations of TMJs were performed. The graded opening bite block was successfully applied in all but two patients.

conclusionsIn conclusion, the simple and easy-to-use graded bite block may be a useful addition to the armamentarium of a radiologist performing MRI scans of the TMJ.
