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
This study aims to evaluate the efficacy of percutaneous vertebroplasty in treating compression fractures of the thoracolumbar spine in elderly patients and to analyze factors influencing the improvement of postoperative kyphotic deformity. A retrospective review was conducted of 106 patients treated with percutaneous cement injection at our hospital from January to December 2024. Preoperative and 3-month postoperative measurements included anterior/mid-height ratio of the injured vertebra, wedge angle, and Visual Analogue Scale. Patients were categorized into an improvement group (n = 79) and a non-improvement group (n = 27) based on a wedge angle difference >3.0°. All procedures were completed successfully. At 3 months postoperatively, vertebral height increased compared to preoperative levels, while wedge angle and Visual Analogue Scale decreased (all P < .05). No statistically significant differences existed between groups in gender, time from fracture to surgery, or operative duration (P > .05). Significant differences were observed in postoperative hospitalization duration, bone mineral density, bone cement leakage, and age (P < .05). Spearman analysis revealed correlations between wedge angle change and these factors; logistic regression identified reduced bone mineral density, cement leakage, prolonged postoperative hospitalization, and advanced age as independent risk factors (all P < .05). Percutaneous vertebroplasty restores vertebral height, stabilizes the spine, and provides pain relief, but its kyphosis correction is limited. Factors such as low bone mineral density, leakage, postoperative hospitalization duration, and age warrant attention through targeted interventions to optimize outcomes.
