Venous Thromboembolism Risk Associated With Relugolix-estradiol-norethisterone Acetate Combination Therapy.
Review in Journal of the Endocrine Society, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Background: Relugolix, an oral GnRH receptor antagonist, is effective in treating uterine myomas and endometriosis. However, concerns persist regarding the venous thromboembolism (VTE) risk associated with its combination with oral estradiol (E2) and norethisterone acetate (NETA). Objective: This expert opinion evaluates the thrombotic risk of relugolix combined therapy (relugolix-CT) based on pharmacological data, clinical trials, and regulatory assessments. Methods: A review of pivotal trials (LIBERTY 1, LIBERTY 2, SPIRIT 1, SPIRIT 2), regulatory reports (European Medicines Agency, Food and Drug Administration), and real-world safety data was conducted, focusing on hemostatic effects and VTE risk. Results: Relugolix monotherapy reduces estrogen levels, leading to minor decreases in coagulation factors. While E2 and NETA mitigate hypoestrogenic effects, concerns about their prothrombotic potential remain. However, clinical trials and postmarketing surveillance have not shown a significant increase in VTE risk. A meta-analysis suggests that E2-based regimens have a lower thrombotic risk than ethinylestradiol-based therapies. Conclusion: The VTE risk of relugolix-CT appears lower than that of traditional combined oral contraceptives. Nonetheless, patient selection is essential, particularly for those with thrombotic risk factors. Continued real-world surveillance is crucial to refining its safety profile in clinical practice.
