1 · What the graph read from it

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.

2 · The registry

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

purposeThe factors that predict delayed union in patients undergoing surgical management of osteoporotic vertebral compression fractures (OVCFs) have not been definitively established. This review aimed to comprehensively identify and analyze these factors to inform clinical practice and improve patient outcomes.

methodsFour English and three Chinese databases were systematically searched from inception to July 1, 2025. Stata 16.0 was utilized for data analysis. Predictors of delayed union reported in two or more studies were combined. Sensitivity analyses were performed to ensure stability and reliability. Egger and Begg's tests were applied to evaluate publication bias.

resultsThis review included 14 studies with a total of 2,349 patients and found that the incidence of delayed union after surgical treatment in patients with OVCFs ranged from 7.86 to 50%. Twelve predictors associated with delayed union were included in this meta-analysis. Ten of them had a statistically significant effect on delayed union, covering baseline characteristics, biological and molecular factors, outcome measures, and therapeutic interventions. The most frequently reported predictor was high bone mineral density (OR = 0.173, 95% CI: 0.068 to 0.442, p < 0.001), followed by advanced age (OR = 1.122, 95% CI: 1.046 to 1.203, p < 0.001), combined diabetes (OR = 2.066, 95% CI: 1.697 to 2.514, p < 0.001), Bone Morphogenetic Protein-2/7 (OR = 0.890, 95% CI: 0.792 to 0.999, p = 0.048), and vertebral height restoration rate (OR = 1.848, 95% CI: 1.246-2.742, p = 0.002).

conclusionsA total of ten factors were identified as significant predictors of delayed union, encompassing five baseline characteristics, three biological molecular factors, one outcome measure, and one therapeutic intervention. The findings of this study highlight the importance of comprehensive pre- and post- operative evaluations, along with careful surgical techniques, in reducing the risk of delayed union in patients with OVCFs.
