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
backgroundOsteoporotic vertebral compression fractures (OVCFs) are common in patients with osteoporosis and have a significant impact on quality of life. Vertebroplasty is a common treatment, but the risk of postoperative refracture remains a complex issue. Identification of associated risk factors is essential to improve patient prognosis.
methodsThis retrospective cohort study included 180 patients aged 60 years and older with osteoporotic thoracolumbar fractures who underwent vertebroplasty between January 2021 and September 2022. Several variables were collected from the electronic medical record system. Univariate and multivariate Cox regression models were used to identify independent risk factors for refracture. Kaplan-Meier survival analysis was used to calculate non-refracture survival, and ROC curves were used to assess predictive ability.
resultsDuring the follow-up period ranging from 12 to 33 months (mean: 19.28 ± 7.84 months), 24 patients experienced vertebral refracture. Univariate and multivariate Cox regression analyses identified four independent risk factors: bone cement distribution pattern, bone mineral density (BMD), anterior vertebral height ratio (AVHR), and Cobb angle restoration. The compact type of bone cement distribution, lower BMD, higher AVHR, and greater Cobb angle restoration increased the risk of refracture. The combined prediction of these factors had a higher predictive power (AUC = 0.89).
conclusionsBone cement distribution pattern, BMD, AVHR, and Cobb angle restoration are important risk factors for refracture after vertebroplasty in osteoporotic thoracolumbar fractures. The combined assessment of these factors can better predict the risk of refracture.
