Subdermal contraceptive implant migration to the pulmonary vasculature: A case report.
Article in Case reports in women's 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
Subdermal implants are highly effective long-acting reversible contraceptives. Rarely, they may migrate intravascularly. This report concerns the case of a 22-year-old woman who presented for removal of a non-palpable etonogestrel implant. Imaging revealed migration to the pulmonary vasculature. Surgical consultation confirmed intravascular embolization to the basal anterior segmental artery of the left lower lobe. Extraction of the implant was performed without complications. Subdermal contraceptive implant embolization into the pulmonary vasculature is an emerging iatrogenic complication. The clinical relevance of this complication lies not only in its potential for pulmonary damage but also in its diagnostic challenge and management complexity. While endovascular retrieval should be considered the first-line approach, especially in cases detected early, in the present case this was not feasible due to endothelialization; thoracotomy ensured safe removal. Pulmonary migration of contraceptive implants is rare but potentially serious. Delayed diagnosis may preclude endovascular removal.
