Relationship between global muscle atrophy and sagittal imbalance in patients with degenerative lumbar scoliosis: a study based on three-dimensional reconstruction.

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
purposeTo explore the three-dimensional (3D) characteristics of the paraspinal muscle (PSM) and the risk factors associated with sagittal imbalance (SI) in degenerative lumbar scoliosis (DLS) patients.
methods168 patients with DLS were included in this study. We evaluated radiographic parameters, including spinopelvic parameters, apical intervertebral height, mean osteophyte formation score, apical vertebral rotation, mean facet degeneration, vertebral bone quality, mean intervertebral disc degeneration, mean modic changes, and relative muscle volume (rMV) of the PSM, including the paraspinal extensor muscle (PEM) and psoas major (PS), and fat infiltration (FI) of the PSM.
resultsSignificant differences were found in the rMV of PEM, PS, and FI of PEM between the concave and convex sides of the spine (p < 0.001). Seventy-two patients comprised the SI group, and 96 comprised the sagittal balance (SB) group. All the rMV of the PSM of the patients with SI were smaller than those of those with SB (p < 0.05). The patients with SI were older than those with SB (p = 0.001). Additionally, in comparison to those with SB, the patients with SI had less LL and SS (p < 0.05), as well as an increased SVA and PT (p < 0.05). Furthermore, logistic regression revealed that age, LL, and the rMV of PS on the concave side influenced sagittal imbalance.
conclusionsThis study revealed that the degeneration of the PSM on both sides was asymmetric and that aging, loss of LL, and global atrophy of the PSM, especially the concave side of PS, were significantly correlated with SI in patients with DLS.
