Ovarian Myxoma in a Patient With Missed Abortion: A Diagnostic Dilemma.
Article in Cureus, 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
Ovarian myxoma is a rare benign mesenchymal tumor. It can be completely asymptomatic and is difficult to differentiate from other ovarian masses before surgery and final histopathology. We report a case of a 28-year-old primigravida who presented with a missed abortion at 11 weeks. Transvaginal ultrasonography incidentally showed a 6.5 × 5.7 cm complex solid-cystic right adnexal lesion in the pouch of Douglas. She was asymptomatic from the mass. After dilatation and evacuation for missed abortion, the patient was evaluated for an ovarian mass, and tumor markers were found negative. Repeat ultrasonography showed a heterogeneous lesion with coarse hyperechoic foci and posterior acoustic shadowing, suggesting a right ovarian teratoma. The patient was taken for laparotomy, wherein an 8 × 8 cm solid-cystic mass was found in the right ovary, and right ovarian cystectomy was done. Intraoperative scrape cytology came back negative for malignancy and showed columnar cells, squamous cells, and mature adipose tissue, which favored a benign cystic teratoma. Histopathology showed a thick collagenous capsule and stellate cells in abundant myxoid stroma without atypia. On immunohistochemistry, the tumor cells were positive for vimentin and negative for desmin and cytokeratin. The final diagnosis was ovarian myxoma. The postoperative course was uneventful, and the patient was discharged on postoperative day 5. There was no recurrence at one-year follow-up. This case shows that ovarian myxoma can mimic a mature cystic teratoma on imaging, gross examination, and cytology, and that the final diagnosis depends on histopathological examination (HPE) supported by immunohistochemistry.
