The predictive value of endplate morphology and pedicle screw bone quality score on screw loosening after single-level lumbar spinal fusion surgery.

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
objectiveThis study aims to explore the predictive value of endplate morphology and pedicle screw bone quality score on screw loosening after single-level lumbar spinal fusion surgery.
methodsA retrospective analysis was conducted on the clinical data of 207 patients who underwent single-level lumbar spinal fusion (34 in the screw loosening group and 173 in the non-screw loosening group). Univariate analysis and binary logistic regression model analysis were performed using SPSS 27.0. MedCalc 23 was used to plot the receiver operating characteristic (ROC) curve to evaluate diagnostic efficacy.
resultsThrough comparative analysis of clinical data, we found statistically significant differences between the two groups in terms of endplate morphology, lumbar CT values, and PBQ scores(P<0.05). The results of the binary logistic regression analysis indicated that endplate morphology (OR = 17.088, 95% CI: 3.886-75.142; p < 0.001) and PBQ score (OR = 3.347, 95% CI: 1.473-7.603; p = 0.004) are independent risk factors for screw loosening after single-level lumbar spinal fusion surgery. The ROC analysis showed that the area under the curve (AUC) for endplate morphology was 0.731 (95% confidence interval [CI]: 0.665-0.790), with the optimal threshold representing irregular endplate morphology (sensitivity: 94.1%, specificity: 52.0%). The AUC for the PBQ score was 0.791 (95% CI: 0.729-0.844), with an optimal threshold of 3.198 (sensitivity: 91.2%, specificity: 61.8%). Furthermore, the predictive model constructed using both endplate morphology and PBQ score had an AUC of 0.870 (95% confidence interval: 0.817-0.913), with a maximum Youden index of 0.668, yielding a diagnostic sensitivity of 88.2% and specificity of 78.6%.
conclusionEndplate morphology and pedicle screw bone quality score have significant reference value for diagnosing screw loosening after single-level lumbar spinal fusion surgery.
