1 · What the graph read from it

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.

2 · The registry

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

Objectives: This study aims to evaluate the safety and efficacy of ovarian vein embolization combined with polidocanol sclerotherapy for Venous-origin chronic pelvic pain (VO-CPP) and to elucidate potential risk factors affecting prognosis. Methods: A total of 158 patients diagnosed with VO-CPP who underwent embolization were enrolled between October 2019 and August 2024. Patients were followed up at 1 month, 3 months, 6 months, and then annually after the embolization through phone calls and outpatient clinic visits. The primary outcome was the proportion of patients achieving an effective response, defined as a decrease in the Visual Analog Scale (VAS) by at least 50% at the final follow-up. Secondary outcomes included technical success, the time to onset of pain relief, complication rates, and risk factors for poor prognosis. Results: Technical success was achieved in 100% of cases, with most patients experiencing significant pain relief by 3 months post-embolization. The VAS scores at each time point after embolization were significantly lower than those recorded before the procedure, with all differences being statistically significant ( Conclusion: Ovarian vein embolization combined with polidocanol sclerotherapy is a feasible and safe endovascular procedure for the treatment of VO-CPP. Multiparous and comorbidities were the independent risk factor associated with poor prognosis.
