Group 4 pulmonary hypertension due to choriocarcinoma after molar pregnancy: case report and review.
Review in Archivos de cardiologia de Mexico, 2025. 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
A 46-year-old Mexican woman developed type 4 pulmonary hypertension (PH) due to tumor embolism from choriocarcinoma (CC), which is an uncommon presentation of this malignancy. She presented with precordial pain, dyspnea, and rapid functional decline. Imaging revealed obstructive thrombi in the pulmonary arteries, initially suggestive of operable chronic thromboembolic PH (CTEPH). A bilateral subsegmental pulmonary thromboendarterectomy was performed, the standard treatment for CTEPH, aimed at removing obstructive material and restoring hemodynamic stability. However, histopathological examination of the surgical specimens showed malignant cells positive for human chorionic gonadotropin, confirming CC as the source of tumor emboli and leading to reclassification of her condition as type 4.2.2 PH. The patient died intraoperatively due to severe airway bleeding and inability to wean from cardiopulmonary bypass.
