Three-dimensional computed tomography morphometric analysis of lumbar endplates in Chinese young adults.
Article in Frontiers in surgery, 2026. 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
Purpose: To analyze the morphological characteristics of the lumbar 4 (L4)- Sacral 1 (S1) endplates in the Chinese young adults lumbar spine based on three-dimensional (3D) computed tomography (CT) scans, providing a reference for the design and application of intervertebral fusion devices. Methods: We collected data from 33 patients with healthy lumbar spines and performed lumbar CT scans and 3D model reconstructions of the vertebral endplates. Sagittal and coronal dimensions of the concave areas of the endplates were measured from the L4 superior endplate to the S1 superior endplate, as was the depth of the most concave point in the concave areas of the endplates. The endplate morphology was classified and compared between sexes. Results: In the sagittal plane, uniformly concave endplate, 20.6%; asymmetric concave, 32.7%; flat-bottomed concave, 12.1%; and flat endplate, 34.5%; in the coronal plane, uniformly concave endplate, 32.1%; asymmetric concave, 0.6%; flat-bottomed concave, 52.7%; and flat endplate, 14.5%. There were no statistically significant differences in the sagittal and coronal morphology of the lower lumbar endplates between sexes ( Conclusions: The sagittal plane morphology of the lower lumbar endplate is mostly concave, whereas the sagittal plane morphology of the S1 endplate is mostly flat. Asymmetric endplates are less common in the coronal plane, and the endplates in the coronal plane are mostly symmetrically distributed. Sex has no significant effect on the morphology of the endplates.
