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
Introduction: Spinal surgery for osteoporotic vertebral fractures using implants often results in implant failure owing to poor bone quality. We developed a new augmentation technique using calcium phosphate cement (CPC) for percutaneous pedicle screws (PPSs). This study evaluated the reinforcement effect of CPC on the initial fixation strength of PPSs in synthetic bone specimens. Methods: Using the X-Needle Results: In the pull-out test, the maximal pull-out strength in the CPC24 group was significantly greater than that in the control and CPC0 groups. Pull-out strength in the CPC10 and CPC24 groups increased to 121.1% and 165.1% of that of the control group, respectively. In the toggle test, the CPC24 group showed significantly higher values for both cycles and load compared to the control group. Conclusions: The X-Needle
