Lumbar offset distance: A simplified metric for evaluation of the lumbar spine alignment.

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
Background: A healthy lower back is essential for optimal spinal function and overall wellness. Magnetic resonance imaging (MRI) has become the gold standard in assessing lumbar spine disease. This article aims to evaluate the precision and efficacy of the lumbar offset distance (LOD) as a novel MRI parameter designed to determine the lumbar spine alignment. normally measured as we compared it to a new parameter based on length. Materials and Methods: Supine sagittal magnetic resonance images of 101 patients who underwent lumbar spine MRI scans were analyzed. We focused on L1-L5 lumbar lordosis angle (LLA) and LOD to assess lumbar spine alignment. Diagnostic cutoff values for LOD measurements were determined, and their diagnostic accuracies were evaluated. Results: The normal LLA in our dataset was 23°-45°, and the normal LOD was 5-15 mm. Using linear regression, the range of 6-14 mm correlates to the LLA range of 20°-45°, which would define the standard lumbar offset as normal between 6 and 14 mm. Hence, lumbar hypolordosis was defined as <6 mm, and lumbar hyperlordosis was defined as more than 14 mm. Our study showed a good correlation between the LOD and LLA and is particularly useful in identifying cases of normal lumbar lordosis, hypolordosis, and hyperlordosis. Conclusion: Linear measurements show good diagnostic accuracy of LOD in evaluating lumbar spinal alignment, including normal alignment, hypolordosis, and hyperlordosis.
