MRI-based vertebral and endplate bone quality scores for assessing patient suitability in oblique lumbar interbody fusion with anterolateral screw fixation.

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
backgroundOblique lumbar interbody fusion with anterolateral screw fixation (ASF) has been used to treat lumbar degenerative disease. Cage subsidence, a common OLIF complication, is significantly affected by low bone mineral density. Although MRI-based vertebral bone quality (VBQ) and endplate bone quality (EBQ) scores relate to bone density, their impact on OLIF with ASF remains unstudied.
methodsThis study reviewed data from patients who underwent OLIF combined with ASF from January 2021 to May 2023. We assessed cage subsidence (CS) by postoperative CT, while VBQ score and EBQ score were derived from MRI scans. Receiver operating characteristic (ROC) curve analysis was employed to assess the predictive accuracy of VBQ score and EBQ score.
resultsThis study included a total of 219 patients, with 127 in the single-level group and 92 in the double-level group. The overall rate of CS in this study was 30.6%. For patients who experienced CS, the average VBQ score was 3.110 ± 0.639. Conversely, for patients without CS, the average VBQ score was lower at 2.635 ± 0.477 (P < 0.0001). In patients undergoing single-level OLIF-ASF, the VBQ scores were 3.499 ± 0.658 in patients with CS and 2.730 ± 0.496 in patients without CS (P < 0.0001). For double-level OLIF-ASF group, VBQ scores were 2.812 ± 0.438 in the CS subgroup and 2.461 ± 0.389 in the NCS subgroup (P = 0.0003). In the single-level group, we also assessed the EBQ score, which showed 2.750 ± 0.478 in the CS subgroup and 2.459 ± 0.492 in the NCS subgroup (P < 0.0001). The optimal cutoff value for the global VBQ score was determined to be 2.800. For the single-level group, the area under the curve (AUC) for VBQ score was 0.808, with an optimal cutoff value determined at 3.490 .In the double-level group, the AUC for VBQ score was 0.724, with the optimal cutoff value identified as 2.705. The AUC for EBQ score in the single-level group was 0.740, and the optimal cutoff value was determined to be 2.905 .
conclusionsThe study found that for single-level cases, OLIF-ASF is advised only if VBQ is below 3.49 or EBQ is below 2.905. For double-level cases, OLIF-ASF is advised only if VBQ is below 2.705.
