Postural and biomechanical insights in disc displacement with reduction.

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
backgroundAlthough the relationship between temporomandibular disorders and posture has been addressed in many studies, a complete consensus has not yet been reached. This study aimed to evaluate global posture, cervical, thoracic and lumbar mobility, and the biomechanical characteristics of muscles in individuals with disc displacement with reduction.
methodsA total of 70 participants were included in the study, consisting of 37 healthy individuals in the control group and 33 individuals in the study group. The participants included in the study were assessed for temporomandibular joint range of motion, pressure pain threshold in regions related to the temporomandibular disorders (lateral capsule, masticatory muscles and upper trapezius), global posture and thoracic and lumbar spine mobility, cervical posture and mobility, and the biomechanical characteristics (elasticity, stiffness and tone) of the paravertebral muscles, masticatory muscles and upper trapezius. The assessment was conducted using a digital caliper, an analog algometer, a spinal mouse, a universal and modified universal goniometer, and MyotonPRO, respectively.
resultsCervical and temporomandibular joint range of motion were similar in both groups. The study group showed lower pressure pain threshold overall, except in the left upper trapezius and right anterior temporalis. The biomechanical characteristics (elasticity, stiffness and tone) of the masseter muscle and paravertebral muscles were also comparable, except for reduced elasticity in the left semispinalis muscle. Global posture and mobility (cervical, thoracic and lumbar) were alike in both groups.
conclusionsThis study showed that young adults with disc displacement with reduction largely have similar global posture, mobility (cervical, thoracic and lumbar) and muscle biomechanical characteristics (elasticity, stiffness and tone) compared to healthy individuals. However, their pressure pain threshold, especially at the joint capsule and most measurement points, was lower, except for a few areas.
