The head position and cervical alignment in patients with Chiari malformation: A retrospective case-control study.
Article in Journal of craniovertebral junction & spine. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Aim and Background: This study aimed to investigate the relationship between cervical spinal alignment and the center of gravity (COG) of the head in patients with Chiari malformation (CM) compared to healthy individuals. CM is characterized by the herniation of posterior fossa structures through the foramen magnum, potentially affecting head positioning and craniovertebral junction biomechanics. Understanding these biomechanical changes is crucial for improving diagnostic and treatment strategies. Materials and Methods: This retrospective study included 102 CM patients and 71 healthy controls. Radiological measurements were obtained from cervical X-rays, with seven reference points used to calculate angles related to head positioning and cervical curvature. Angular parameters, including cranial incidence (CI), cranial slope (CS), cranial tilt (CT), C7 slope (C7S), and spinocranial angle (SCA), were analyzed to determine correlations with the COG of the head. Statistical analyses were performed using Results: CM patients had significantly higher CI, CT, STT, and SCA angles compared to controls ( Conclusion: CM patients exhibit distinct biomechanical alterations, including an anterior shift of the COG and a more flexed head position. These findings highlight the potential of angular measurements as noninvasive diagnostic tools for CM. Future studies should explore the implications of these biomechanical changes on CM progression and treatment outcomes.
