Utilizing MRI and CT to identify risk factors associated with cage subsidence.
Article in European journal of medical research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
objectivesTo identify risk factors associated with cage subsidence (CS) following single segment transforaminal lumbar interbody fusion (TLIF) and unilateral biportal endoscopic lumbar interbody fusion (ULIF) and to compare the predictive performance of various bone quality assessment methods using MRI and CT images.
methodsA total of 226 patients from 2021 to 2023 who underwent ULIF/TLIF because of lumbar disc herniation and lumbar spinal stenosis were enrolled. The subsidence of the cage into the vertebral body exceeding 2 mm was defined as CS and diagnosed using CT scans. Immediate endplate destruction (IED) was defined by CT and VBQ was measured through T1-weighted lumbar MRI. The independent sample t-test was employed to examine the risk factors associated with CS. Additionally, risk factors associated with CS were identified using logistic regression analysis. Lastly, the comparative predictive values were assessed through ROC curve analysis.
resultsLogistic regression analysis revealed that increased postoperative posterior disc height (PPDH), higher segmental VBQ scores, higher mean VBQ (M-VBQ) scores, decreased segmental HU values, decreased mean HU (M-HU) values and immediate endplate destruction (IED) were associated with the occurrence of CS. The area under the curve (AUC) of the VBQ score was higher than that of the HU value, both in segment and in average.
conclusionsThe incidence of CS was lower in ULIF compared to TLIF. High VBQ scores, low HU values, high PPDH and the presence of IED were associated with an increased risk of CS. Notably, the predictive value of both VBQ scores and HU values were high for CS, with the former potentially outperforming the latter.
