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
Objective: This study aimed to investigate the clinical value of combining pedicle bone quality scoring and Hounsfield units (HUs) in predicting the risk of cage subsidence following single-segment lumbar fusion surgery. Methods: We conducted a retrospective analysis of clinical data from 160 patients who underwent single-segment lumbar fusion surgery at Panyu District Traditional Chinese Medicine Hospital between January 2017 and May 2023. Clinical data comparisons and multivariate logistic regression analyses were performed using SPSS 27.0. Receiver operating characteristic (ROC) curves were generated using MedCalc 23 to evaluate diagnostic efficacy. Results: Comparative analysis of clinical data revealed statistically significant differences between the two groups in terms of age, hypertension, HUs, vertebral body quality (VBQ) scores, and pedicle bone quality (PBQ) scores ( Conclusion: Pedicle bone quality scoring and HUs provide significant reference value in diagnosing cage subsidence following single-segment lumbar interbody fusion. The predictive model constructed through the combined assessment of these two factors demonstrated superior diagnostic efficacy.
