A CT-based radiographic analysis of parameters of congenital lumbar neuroforaminal stenosis.
Article in Journal of spine surgery (Hong Kong), 2025. 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
Background: Quantitative parameters for the diagnosis of congenital lumbar stenosis (CLS) have yet to be universally accepted. This study establishes parameters for congenital stenosis of lumbar neuroforaminal dimensions (LNFD) using computed tomography (CT), assessing the influences of patient sex, race, and ethnicity. Methods: Measurements of LNFD were performed on CT scans from 1,000 patients aged 18-35 years without spinal pathology. Results: Irrespective of vertebral level, mean anatomic LNFD measurements were as follows: 8.66±2.1 and 8.76±3.14 mm for left and right widths, 17.76±2.74 and 17.7±3.26 mm for left and right heights, and 133.12±34.72 and 133.4±33.86 mm Conclusions: This study reports measurements of LNFD via CT of 1,000 patients to establish quantitative thresholds for diagnosis of neuroforaminal stenosis. Patient sex, race, and ethnicity highlighted significant findings per vertebral level, but not irrespective of vertebral level. These findings may help solidify anatomic thresholds of foraminal stenosis via radiographic imaging and establish the foundation for future research on the diagnosis of lumbar neuroforaminal stenosis.
