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
Objective: To evaluate the differences in efficacy between polyvinyl alcohol colorless embolic microspheres (8Spheres Methods: We included 259 patients from 12 hospitals who underwent uterine artery embolization for symptomatic uterine fibroids. We collected preoperative general conditions, menstrual status, and uterine and fibroid sizes as indicated by magnetic resonance imaging, as well as changes in ovarian hormone levels before and 6 months after the procedure. Differences in uterine fibroid scores and health-related quality of life scores between the two types of microspheres were compared using analysis of covariance (ANCOVA). Differences in the largest fibroid volume, uterine volume, total menstrual bleeding score, and ovarian hormone levels were compared using Results: There was no significant difference in clinical efficacy between the two types of microspheres at 6 months postoperatively (P=0.4081). No significant differences were observed in uterine fibroid volume or symptom-related scores.There were no significant differences in ovarian hormone levels between the two groups or within each group before and after the procedure. Conclusion: The use of 8Spheres® is effective for symptomatic uterine fibroids and is comparable to the currently clinically used Embosphere
