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

We propose a novel method, the epinephrine compression method (Epi-pledget), as a hemostasis method for ovarian cystectomy. A total of 179 patients undergoing laparoscopic ovarian cystectomy with stripping were randomly allocated into three groups: the bipolar coagulation group, the Epi-pledget group, and the coagulation after Epi-pledget (Epi & Coagulation) group. Serum anti-Müllerian hormone (AMH) levels and antral follicle count (AFC) by ultrasonography were measured to determine the preservation of ovarian function. To evaluate the postoperative ovarian cellular proliferative activity and tissue damage in a mouse model, we operated on the ovaries of mice with an artificial incision injury and applied two hemostatic methods: coagulation and Epi-pledget. Eight weeks after surgery, the AMH rate significantly decreased in the bipolar coagulation group compared with the Epi-pledget group. The AFC decline rate was also significantly greater in the coagulation group than the Epi-pledget group. Specifically, patients with endometrioma had a significantly greater decline of serum AMH in the coagulation group than the Epi-pledget group. In a histopathological analysis in mice, the Epi-pledget group showed ameliorated fibrotic changes and necrotic findings in the injured lesion compared with the bipolar coagulation group. The Epi-pledget method for ovarian stripping has an additional benefit of maximizing the preservation of the ovarian reserve, especially for the endometriotic ovarian cyst type.
