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
objectiveTo analyze the risk factors for secondary cauda equina injury in lumbar spinal stenosis using LASSO logistic regression and to construct a risk prediction model in the form of a nomogram.
methodsPatients with lumbar spinal stenosis were divided into a secondary injury group (90 cases) and a non-secondary injury group (110 cases). LASSO logistic regression was applied, and a risk nomogram was generated. The predictive efficacy of the model was evaluated using receiver operating characteristic (ROC) curves and calibration curves.
resultsThe ROC curve analysis showed that the area under the curve (AUC) of the risk nomogram model was 0.865 (95% CI: 0.755-0.948), with a sensitivity of 91.11% (82/90), specificity of 93.64% (103/110), and accuracy of 92.50% (185/200). The risk nomogram model demonstrated good fit (χ
conclusionAge > 60 years, disease duration > 1 year, multiple stenosis segments, small median sagittal diameter, small cross-sectional area of the spinal canal, and shorter segment length are risk factors for secondary cauda equina injury in patients with lumbar spinal stenosis. The risk prediction model based on this nomogram has good clinical application value.
