Effect of Thoracolumbar Vertebral Body Fractures on the Prognosis of Dropped Head Syndrome.

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
Introduction: In dropped head syndrome (DHS), the factors contributing to the prognosis due to conservative treatment have been unclear. The purpose of this study was to investigate the effect of spinal malalignment due to pre-existing thoracolumbar vertebral fractures on the improvement rate of conservative treatment of DHS. Methods: Overall, 90 patients with DHS who visited our hospital and underwent conservative treatment for 6 months were included in the study. Patients were divided into 2 groups, Group F with and Group N without thoracolumbar vertebral fracture, and their improvement rate and spinal parameters were compared and statistically examined. Results: Group F had a significantly larger sagittal vertical axis (SVA) and pelvic incidence minus lumbar lordosis (PI-LL). Cervicothoracic spine alignment did not differ between Groups F and N. The improvement rate of Group F was significantly lower than that of Group N (Group F: 18.8%, Group N: 54.1%). Conclusions: DHS with thoracolumbar vertebral fracture has significantly large SVA and PI-LL, which would be a poor prognostic factor of conservative treatment.
