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
Background: Percutaneous vertebroplasty (PVP) for upper and middle thoracic osteoporotic vertebral compression fractures (OVCFs) is challenged by technical difficulties and safety concerns, which drive the need for innovative techniques to optimize its efficacy. The purpose of this study was to delineate the technical characteristics of a novel methodology and to conduct a comparative analysis of its efficacy against bilateral transpedicular puncture PVP. Methods: A retrospective study was conducted on consecutive patients undergoing PVP for upper/middle thoracic OVCFs at the Second Affiliated Hospital of Chongqing Medical University (Chongqing, China) between January 2019 and December 2024. Patients were allocated to either the unilateral transpedicular puncture lateral injection (UTPLI) or the conventional bilateral transpedicular puncture (BTP) group based on the surgical timeline, with earlier cases undergoing BTP and later ones UTPLI. Baseline characteristics, operative time, estimated blood loss, cement volume, visual analogue scale (VAS), Oswestry disability index (ODI), vertebral and segmental kyphosis angles, anterior/middle/posterior vertebral heights, and postoperative cement distribution indices were recorded and compared between the two groups. Data were analyzed with SPSS software (version 26.0) using Chi square, Results: A total of 57 patients were enrolled (UTPLI group=21, BTP group=36). The UTPLI group had a shorter operation time (18.00±9.00 min vs. 25.00±9.00 min, P=0.002) and less estimated blood loss (3.93±1.22 mL vs. 5.13±1.37 mL, P=0.002). No significant intergroup differences were found in VAS, ODI, kyphosis angles (vertebral, segmental, thoracic), vertebral heights (anterior, middle, posterior), baseline data, bone cement leakage, cement dispersion index, or spatial distribution scores, either preoperatively or postoperatively (P>0.05). Conclusion: The UTPLI technique is a viable alternative to BTP PVP for upper and middle thoracic OVCFs. It reduced operative time and blood loss while achieving comparable outcomes.
