Impact of vasopressin-assisted laparoscopic endometrioma excision on ovarian reserve: a randomized controlled trial.
Article in Frontiers in reproductive health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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: Laparoscopic cystectomy is the standard surgical treatment for ovarian endometrioma; however, inadvertent removal of healthy ovarian tissue and thermal injury during hemostasis may compromise ovarian reserve. Vasopressin injection has been proposed as a surgical adjunct to reduce bleeding and limit the need for electrocoagulation, thereby potentially minimizing ovarian damage. However, evidence regarding its effectiveness in preserving ovarian reserve remains limited. Methods: This randomized controlled trial was conducted at a tertiary university-affiliated medical center between September 2018 and July 2021. Seventy-five women undergoing laparoscopic cystectomy for unilateral ovarian endometrioma were stratified according to baseline serum anti-Müllerian hormone (AMH) levels and randomly assigned to either a vasopressin-assisted surgery group or a control group. The primary outcome was the change in serum AMH level 12 months after surgery. Secondary outcomes included operative parameters, including cyst stripping time and time required for bleeding control. Outcomes were analyzed using intention-to-treat and per-protocol approaches. Longitudinal changes in AMH were evaluated using linear mixed-effects models. Results: In the intention-to-treat analysis, vasopressin injection significantly reduced the time required for cyst stripping (8.9 ± 7.9 vs. 14.4 ± 13.7 min, Conclusion: Although vasopressin reduced operative time and electrocoagulation exposure during endometrioma surgery, it did not prevent postoperative decline in ovarian reserve.
